Data will remain intact in the database, but the database is not automatically written to a file (use the SAVE command to write the database to a file).

This command is part of the suite of commands available to find gaps and repair the topology of a model imported from a CAD system through the Default IGES option.. These commands are made available if, during a CAD import operation, ANSYS detects topological defects (small gaps, large holes, or overlapping entities). You cannot use the GAPMERGE command on a model after issuing the GAPFINISH command; however, you can continue to repair the model with the geometry repair commands.

Main Menu >Preprocessor >Topo Repair >Finish

Lists all joined or disjoined lines in a model (for models imported from CAD files).

PREP7:CADRepair

	Mp Me St DY LP Th E3 E2 FL PP ED

Label defining the type of plot:

OPEN - Lists all disjoined edges. This is the default option.

CLOSED - Lists all seam lines that are currently "sewn" to adjacent areas.

Disjoined lines are those lines which have only one area attached to them. Typically, these occur around gaps in the model and should be merged with adjacent disjoined lines using the GAPMERGE command (topological repair) or ARFILL command (geometry repair).

This command is available for both topological and geometric repair for models imported from CAD files through the Default IGES option.. If topological repair is active, you can specify what is listed through the GAPOPT, OESELE command.

Main Menu >Preprocessor >Geom Repair >Close Edges

Main Menu >Preprocessor >Geom Repair >Open Edges

Main Menu >Preprocessor >Topo Repair >Close Edges

Main Menu >Preprocessor >Topo Repair >Open Edges

Merges adjacent disjoined lines (for models imported from CAD files).

PREP7:CADRepair

	Mp Me St DY LP Th E3 E2 FL PP ED

Label defining the type of merge operation.

TOLER - Disjoined lines are merged if they are within the tolerance factor specified by the GAPOPT command.

ITER - Disjoined lines are merged through an iterative merging process, where a series of merges occur starting with the tolerance factor specified in VAL1 until the value specified in VAL2 is reached. The merges occur at increments specified through VAL3. By default, VAL1 is set to its minimum value (1), VAL2 is set to its maximum value (10), and VAL3 is set to 1.

While the Lab = ITER options provides a robust, automatic method for "sewing" gaps, it also requires considerable processing.

This command is part of the suite of commands available to repair the topology of a model imported from CAD systems through the Default IGES option (see Chapter 6 of the ANSYS Modeling and Meshing Guide). These commands are made available if, during a CAD import operation, ANSYS detects topological defects (small gaps, large holes, or overlapping entities). You cannot use the topological repair commands on a model after issuing the GAPFINISH command; however, you can continue to repair the model with the geometry commands.

TOLER - Set tolerance for the GAPMERGE (used only for manual, not iterative, merging), GAPLIST, and GAPPLOT commands as a factor, defined by Value, times the default tolerance. By default, Value is set to its minimum value.

OESELE - Determines what will be displayed by the GAPLIST and GAPPLOT commands. Value can be:

ALL - GAPLIST and GAPPLOT will display all currently existing disjoined edges with both small gaps and large holes. This is the default option.

MERGE - GAPLIST and GAPPLOT will display all open edges that can be merged with the current tolerance.

REMAIN - GAPLIST and GAPPLOT will display all open edges that will remain after merging is performed using the current tolerance.

Gauges the problem domain for an edge-element formulation.

SOLUTION:AnalysisOptions

	Mp Me -- -- -- -- E3 -- -- PP ED

Type of gauging performed:

TREE - Perform tree gauging of the edge values (default)

OFF - Do not gauge the edge values

The GAUGE command, required for electromagnetic analyses using an edge potential formulation, gauges the problem domain. The ANSYS program performs gauging over all selected elements and nodes to produce a minimal unique degree of freedom set for solution. By default, gauging is performed at the solver level for each solution [SOLVE command or MAGSOLV command]. Gauging sets edge values to zero on the tree branches of a graph. The ANSYS program removes these additional constraints after obtaining the solution; therefore, gauging is transparent to users. The GAUGE,OFF option is intended for expert ANSYS users who want to create their own gauging instead of using default tree gauging.

For more information about gauging, see the ANSYS Theory Reference.

This command is also valid in PREP7.

Generates 2-D or 3-D contact elements.

PREP7:Elements

	Mp Me St DY -- -- -- -- -- PP ED

Name of the component containing nodes on the contact surface [CM]. Assemblies are not permitted.

Name of the component containing nodes on the target surface. Assemblies are not permitted.

Generate NUMC contact elements whose contact node is closest to the centroid of each target element face. If Shape=TRI, the program will generate 2*NUMC CONTAC49 elements for each quadrilateral target element face. (That is, each triangular contact element base will be connected to NUMC contact nodes.) Defaults to an unlimited number of contact elements generated per target face.

Generate contact elements whose contact node is within a radius of RADC measured from the centroid of each target element face. Defaults to no limit on the radius.

Label to identify the target surface of line or shell elements. The top surface will be used unless Tlab = BOT. Tlab is ignored if the target elements are solids.

Label that controls the shape of CONTAC49 element bases. Using the TRI feature can sometimes improve contact performance if the target elements have warped quadrilateral faces:

<blank> - The contact element bases will have the same shape (triangular or quadrilateral) as the corresponding target element faces (default).

TRI - The contact element bases will always be triangular.

Generates 2-D contact (CONTAC48) or 3-D contact (CONTAC49) elements. Each contact element connects nodes on a target element face to a contact node. The "target" end of a contact element is called the contact element base. A target element face is defined as a face on a selected element whose nodes belong to the target component. If the selected element is a solid then the target face must also be external to the model, while for a line or shell element all nodes of the element will belong to the target face. The active element type attribute (TYPE) must be a contact element (CONTAC48 or CONTAC49) and must match the dimensionality of the target element. The other active attributes (MAT, TYPE, REAL, ESYS) will be used for the generated elements. The target elements must be defined before using this command. Midside nodes on target element faces are ignored.

Retrieves a value and stores it as a user-named parameter.

APDL:Parameters

	Mp Me St DY LP Th E3 E2 FL PP ED

The name of the resulting parameter. See *SET for name restrictions.

Entity keyword. Valid keywords are NODE, ELEM, KP, LINE, AREA, VOLU, etc. as shown for Entity= in the table below.

The number of the entity (as shown for ENTNUM= in the table below). A zero (or blank) ENTNUM represents all entities of the set.

The name of a particular item for the given entity. Valid items are as shown in the Item1 columns of the table below.

The number (or label) for the specified Item1 (if any). Valid IT1NUM values are as shown in the IT1NUM columns of the table below. Some Item1 labels do not require an IT1NUM value.

A second set of item labels and numbers to further qualify the item for which data are to be retrieved. Most items do not require this level of information.

*GET retrieves a value for a specified item and stores it as a user-named parameter. An item is identified by various keyword, label, and number combinations. Usage is similar to the *SET command except that the parameter values are retrieved from previously input or calculated results. For example, *GET,A, ELEM, 5, CENT, X returns the centroid x-location of element 5 and stores the result as parameter A. For repeated gets of sequential items, such as from a series of elements, see the *VGET command.

A "get function" is available for some items, and can be used instead of the *GET command. The function returns the value and uses it where the function is input (bypassing the need for storing the value with a parameter name and inputting the parameter name where the value is to be used). For example, assume the average X-location of two nodes is to be calculated. Using the *GET command, parameter L1 can be assigned the X location of node 1 (*GET, L1, NODE, 1, LOC, X), and parameter L2 can be assigned the X location of node 2, then the mid location can be computed from MID=(L1+L2)/2. However, using the node location "get function" NX(N), which returns the X location of node N, MID can be computed directly from MID=(NX(1)+NX(2))/2, without the need for intermediate parameters L1 and L2. Get function arguments may themselves be parameters or other get functions. The get function NELEM(ENUM,NPOS) returns the node number in position NPOS for element ENUM. Combining functions, NX(NELEM(ENUM,NPOS)) returns the X location of that node. Get functions (where available) are shown with the corresponding *GET items in the table below and are summarized at the end of this command description.

Most items are stored in the database after they are calculated and are available anytime thereafter. Items are grouped according to where they are usually first defined or calculated. The sections are shown in the following order: General Items, Graphics Items, PREP7 Items, RUNSTAT Items, Solution Items, POST1 Items, POST26 Items, and OPT Items.

The *GET command is valid in any processor.

Defines a gap condition for transient analyses.

SOLUTION:GapConditions

	Mp Me St -- LP -- -- -- -- PP ED

Node I of gap. If NODE1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI).

Node J of gap (must be different from NODE1). Non-grounded gap nodes must be defined as master degrees of freedom. Grounded gap nodes (i.e., those not defined as MDOF) need not appear elsewhere in the model.

Direction of gap action in the nodal coordinate system (implied from the following force labels): FX FY FZ MX MY MZ.

Stiffness of closed gap (may be positive or negative). Note, high stiffness requires a small integration time step for numerical stability.

Initial size of gap. A zero (or positive) value assumes an initially open gap. A negative value defines an interference condition. For a rotational gap, GAP should be in radians.

Defines a gap condition for the reduced or mode superposition transient (ANTYPE=TRANS) analysis. If used in SOLUTION, this command is valid only within the first load step.

Repeat GP command for additional gap conditions. Gaps are numbered sequentially as input. Note, gaps may be renumbered by the program during the solution (see output listing).

The reduced or mode superposition transient analysis (ANTYPE=TRANS and TRNOPT=REDUC or MSUP) does not allow gap action with the standard ANSYS gap elements. Gap conditions, however, producing the same effect, may be defined. The gap condition simulates the basic gap action of the COMBIN40 element. The gap condition is treated as an explicit force (equal to the interference times contact stiffness) and affects only the load vector calculation and not the reduced stiffness matrix. The interference is calculated from the displacement extrapolated from the previous time points. A gap condition may be defined between a master degree of freedom and ground or another master degree of freedom. Gap nodes not defined as master degrees of freedom are assumed to be grounded. Grounded gap nodes need not be given a spatial location nor do they need to be located on an element. Gap conditions may be defined in parallel (across the same nodes), with varying gap and stiffness values, to simulate a nonlinear (piecewise) force-deflection curve.

The gap direction is determined from the force label input on the GP command, i.e., FX defines a translational gap acting in the UX nodal degree of freedom direction, and MZ defines a rotational gap acting in the nodal ROTZ degree of freedom direction. The actual degree of freedom directions available for a particular node depends upon the degrees of freedom associated with the element types [ET] at that node. For example, degrees of freedom available with BEAM3 elements are UX, UY, and ROTZ only (so that only gap labels FX, FY, and MZ are valid).

If the coordinate systems of the nodes connecting the gap are rotated relative to each other, the same degree of freedom may be in different directions. The gap, however, assumes only a one-dimensional action. Nodes I and J may be anywhere in space (preferably coincident). No moment effects are included due to noncoincident nodes. That is, if the nodes are offset from the line of action, moment equilibrium may not be satisfied.

The contact stiffness value represents the stiffness of the closed gap. Stiffness values are related to the integration time step size and should be physically reasonable. High stiffness will require a small integration time step, otherwise, due to the displacement extrapolation, the solution may go unstable. Negative stiffness values may be used with gaps in parallel to produce a decreasing force-deflection curve.

The gap conditions, if any, should be defined in the first load step. Appearances in succeeding load steps are ignored. The order of specifying the gap nodes is important, i.e., a gap condition connecting two nodes will act differently depending upon which node is specified first on the GP command. For example, for Node 1 at X=0.0, Node 2 at X=0.1, and the gap defined from Node 1 to 2, a displacement of Node 1 greater than Node 2 will cause the gap to close. For the gap defined from Node 2 to 1, a displacement of Node 2 greater than Node 1 will cause the gap to close (like a hook action). In general, the gap closes whenever the separation (defined as U_I - U_J + GAP) is negative. U_I is the displacement of node I, U_J is the displacement of node J, and GAP is the input gap value. The gap force output appears in the printout only for the time steps for which the gap is closed. A negative spring force is always associated with a closed gap (even with the hook option).

This command is also valid in PREP7.

This command is valid in any processor.

Utility Menu >Plot >Multi-Plots

Defines type of graphics display to be used for element plots.

GRAPHICS:SetUp

	Mp Me St DY LP Th E3 E2 FL PP ED

Graphics key:

FULL - Display all model geometry and results for element and results displays.

POWER - Activate PowerGraphics (default when GUI is on).

Notes

/GRAPHICS specifies the type of graphics display that is used for element plots. If Key=POWER, the PowerGraphics capability is activated. PowerGraphics offers a much faster plotting time for large models than the Key=FULL option, and speeds up element, results, area, line, and volume displays.

Results values (both printed and plotted) may differ between the Key=FULL and Key=POWER options because each option specifies a different set of data for averaging and display. For Key=FULL, all element and results values (interior and surface) are included. For Key=POWER, only element and results values along the model exterior surface are processed.

The PowerGraphics option does not support circuit elements. If Key=POWER and circuit elements are present, the non-PowerGraphics display is performed for element displays, and circuit elements are missing for result displays. (To see circuit elements on PLDISP displays, issue /GRAPHICS,FULL.)

Caution: If you have specified one facet per element edge for PowerGraphics displays (via the /EFACET command or via choices from the General Postproc or Utility Menus), PowerGraphics does not plot midside nodes.

PowerGraphics, if on, is bypassed if the /EXPAND command is issued. The /EFACET command is only applicable to element type displays. (See the descriptions of these commands for more information.)

Maximum values shown in plots can differ from printed maximum values. This is due to different averaging schemes used for plotted and printed maximum values. (PowerGraphics displays do not average at geometric discontinuities but the printout in PowerGraphics does average at geometric discontinuities.)

Note-In Full Graphics mode, it is possible to deselect an individual node, select all elements (including the element that contains that node), and then perform post-processing calculations on those elements and have that unselected node not be considered in those calculations. However, if PowerGraphics is active, post-processing always displays based on selected elements.

Commands that are not supported by PowerGraphics are listed below. These commands are executed using the Key = FULL option, regardless of whether PowerGraphics is activated. Only certain options for /CTYPE, DSYS, /EDGE, *GET, /PNUM, /PSYMB, RSYS, SHELL, and *VGET are not supported by PowerGraphics. (See the descriptions of these commands for more information.)

FRONT - If Lab is AXNM, FRONT may also be input.

Ndiv - If Lab is DIVX or DIVY, determines the number of divisions (1-99) that will be applied to the axis.

Kfont - If Lab is LTYP, Kfont is ON (1) or OFF(0). ON will use ANSYS generated fonts for the axis labels, while OFF will use SYSTEM (Windows, X-system, etc.) fonts. The default value is ON (ANSYS fonts).

Sets various line graph display options. Issue /GROPT, STAT to display the current settings. Issue /GROPT, DEFA to reset the default specifications. ANSYS informs you that graph view manipulation is inactive unless you have issued the /GROPT,VIEW,ON command. See the /AXLAB, /GRTYP, /GRID, and /GTHK commands for other graph control options.

This command is valid in any processor.

Specifies the grouping mode combination method.

SOLUTION:SpectrumOptions

	Mp Me St -- LP -- -- -- -- PP ED

Combine only those modes whose significance level exceeds the SIGNIF threshold. For single point, multipoint, or DDAM response (SPOPT,SPRS, MPRS or DDAM), the significance level of a mode is defined as the mode coefficient of the mode, divided by the maximum mode coefficient of all modes. Any mode whose significance level is less than SIGNIF is considered insignificant and is not contributed to the mode combinations. The higher the SIGNIF threshold, the fewer the number of modes combined. SIGNIF defaults to 0.001. If SIGNIF is specified as 0.0, it is taken as 0.0. (This mode combination method is not valid for SPOPT,PSD.)

Label identifying the combined mode solution output.

DISP - Displacement solution (default). Displacements, stresses, forces, etc., are available.

VELO - Velocity solution. Velocities, "stress velocities," "force velocities," etc., are available.

ACEL - Acceleration solution. Accelerations, "stress accelerations," "force accelerations," etc., are available.

This command is also valid for PREP7.

Selects single or multiple Y-axes graph displays.

GRAPHICS:Graphs

	Mp Me St DY LP Th E3 E2 FL PP ED

Axis selection key:

0 or 1 - Single Y-axis. Up to 10 curves scaled to a single Y-axis.

2 - Additional Y-axes (one for each curve) (3 curves maximum). Allows better scaling of curves with widely differing numbering ranges.

3 - Same as 2 but with additional Y-axis and curves projected out of the plane (6 curves maximum). Allows clearer display with an isometric view. The default view when KAXIS=3 is View,1,1,2,3.

Notes

The basic line graph has one or more curves plotted against the same Y and X axes. Multiple curve graphs can also be plotted with individual Y axes and the same X axis. The Y axis of the first curve is referred to as the base Y-axis and the Y axes of the other curves as additional Y axes. Curves are numbered sequentially from 1 (the base curve) in the order in which they are displayed. See the /AXLAB, /GROPT, /GRID, and /GTHK commands for other display options.

This command is valid in any processor.

File name (32 characters maximum). Defaults to Jobname.

File name extension (8 characters maximum). Defaults to GSAV if Fname is blank.

Directory name (64 characters maximum). Defaults to current directory.

This command does not save all graphics settings, but only those that may be reset by the /RESET command. The database remains untouched. Use the /GRESUME command to read the file. Repeated use of the /GSAVE command overwrites the previous data on the file. The following commands are saved by /GSAVE:

This command is valid in any processor.

Turns Graphical Solution Tracking (GST) on or off.

SOLUTION:NonlinearOptions

	Mp Me St -- LP Th E3 E2 FL PP ED

Determines whether the Graphical Solution Tracking feature is active. Specify ON to activate GST, or OFF to deactivate the feature.

For interactive runs using the GUI [/MENU,ON] or graphics [/MENU,GRPH] mode, ANSYS directs GST graphics to the screen. For interactive sessions not using GUI or graphics mode, or for batch sessions, GST graphics are saved in the ANSYS graphics file Jobname.GST.

The GST feature is available only for nonlinear structural, thermal, electric, magnetic, fluid, or CFD simulations. For more information about this feature and illustrations of the GST graphics for each analysis type, see the Analysis Guide for the appropriate discipline. See also the CNVTOL command description in this manual.

Calculates and prints geometry items.

PREP7:Keypoints PREP7:Lines PREP7:Areas PREP7:Volumes

	Mp Me St DY LP Th E3 E2 FL PP ED

Calculates and prints geometry items (centroid location, moments of inertia, length, area, volume etc.) associated with the selected keypoints, lines, areas, and volumes.. Geometry items are reported in the global Cartesian coordinate system. For volumes, a unit density is assumed unless the volumes have a material association via the VATT command. For areas, a unit density (and thickness) is assumed unless the areas have a material (and real constant) association via the AATT command. For lines and keypoints, a unit density is assumed, irrespective of any material associations [LATT, KATT, MAT]. Items calculated by GSUM and later retrieved by a *GET or *VGET commands are valid only if the model is not modified after the GSUM command is issued. This command combines the functions of the KSUM, LSUM, ASUM, and VSUM commands.

Sets line thicknesses for graph lines.

GRAPHICS:Graphs

	Mp Me St DY LP Th E3 E2 FL PP ED

Apply thicknesses as selected from the following labels:

AXIS - Modify thickness of ordinate and abscissa axes on graph displays,

GRID - Modify thickness of grid lines on graph displays.

CURVE - Modify thickness of curve lines (when no area fill [/GROPT]).

Thickness ratio (whole numbers only, from 1 to 10 only):

0 or 1 - Default thickness.

2 - Double the default thickness.

3 - Triple the default thickness.

etc. (up to 10)

Sets line thicknesses for graph lines (in raster mode only). Use /GTHK, STAT to show settings.

This command is valid in any processor.

Utility Menu >PlotCtrls >Style >Graphs

Controls the entities that the GPLOT command displays.

GRAPHICS:SetUp

	Mp Me St DY LP Th E3 E2 FL PP ED

Window number (or ALL) to which this command applies (defaults to 1)

This represents the type of entity to display:

NODE - Nodes

ELEM - Elements

KEYP - Keypoints

LINE - Lines

AREA - Areas

VOLU - Volumes

GRPH - Graph displays

Switch:

0 - Turns the entity type off.

1 - Turns the entity type on.

The /GTYPE command controls which entities the GPLOT command displays. NODE, ELEM, KEYP, LINE, AREA, and VOLU are on by default. When ELEM is activated, you can control the type of element displayed via the /GCMD command (which also controls the type of graph display). When the GRPH entity type is activated, all other entity types are deactivated. Conversely, when any of the NODE, ELEM, KEYP, LINE, AREA, and VOLU entity types are active, the GRPH entity type is deactivated.

The /GTYPE command gives you several options for multi-window layout:

· Two windows (left and right or top and bottom of the screen)

· Three windows (two at the top and one at the bottom of the screen, or one top and two bottom windows

· Four windows (two at the top and two at the bottom)

Once you choose a window layout, you can choose one of the following: multiple plots, replotting, or no redisplay.

This command is valid in any processor.
