Sets the program mode to "batch."

SESSION:RunControls

	Mp Me St DY LP Th E3 E2 FL PP ED

Specifies listing mode during a batch run:

LIST - The batch output will include a listing of the input file.

<blank> - Suppress input data listing.

Notes

Sets the program mode to "batch" when included as the first line on an input file of ANSYS commands. For convenience, this command is automatically recorded on the log file (Jobname.LOG) at the beginning of an interactive ANSYS session so that the log file can be reused later for batch input.

Caution: This command should not be entered directly in an interactive ANSYS session since all subsequent keyboard input is simply copied to a file, without further processing or prompts from the program (use the "system break" to exit the ANSYS program if this occurs).

The recommended method for choosing batch mode, rather than using the /BATCH command, is to use the "ANSYS Batch" button on the ANSYS launcher, or the batch mode entry option on the ANSYS execution command when entering the program.

This command is valid only at the Begin Level.

This command cannot be accessed directly in the menu.

Element numbers of the two intersecting straight pipes. Defaults to the last two straight pipe elements nearest the intersection of the last two runs.

Bend radius. If LR, use long radius standard (1.5 x OD) (default). If SR, use short radius standard (1.0 x OD).

Number of divisions (elements) along bend (defaults to 2). A node is generated at the end of each division.

Number to be assigned to first element of bend (defaults to MAXEL+1).

Element number increment (defaults to 1).

Defines a bend of curved (elbow) pipe elements (PIPE18) in place of the intersection of two previously defined straight pipe elements [RUN]. Two new nodes are generated at the ends of the bend (at the tangency points). A node is also generated at the center of curvature point. The two straight pipes are automatically "shortened" to meet the ends of the bend. The bend specifications and loadings are taken from the corresponding two straight pipes. The flexibility factors are calculated from the internal pressure and EX (evaluated at TAVE) based on the current PPRES and PTEMP command specifications when the element is generated.

ADD - Subsequent values are added to the previous values.

IGNO - Subsequent values are ignored.

Scale factor for the nodal body load values. Zero (or blank) defaults to 1.0. Use a small number for a zero scale factor. The scale factor is not applied to body load phase angles.

Used (only with Lab=TEMP) to calculate the temperature used in the add or replace operation (see Oper) as:

where T is the temperature specified on subsequent BF commands. TBASE defaults to zero.

Notes

Allows repeated nodal body force loads to be replaced, added, or ignored. Nodal body loads are applied with the BF command. Issue the BFLIST command to list the nodal body loads. The operations occur when the next body loads are defined. For example, issuing the BF command with a temperature of 250 after a previous BF command with a temperature of 200 causes the new value of the temperature to be 450 with the add operation, 250 with the replace operation, or 200 with the ignore operation. A scale factor is also available to multiply the next value before the add or replace operation. A scale factor of 2.0 with the previous "add" example results in a temperature of 700. The scale factor is applied even if no previous values exist. Issue BFCUM,STAT to show the current label, operation, and scale factors. Solid model boundary conditions are not affected by this command, but boundary conditions on the FE model are affected. (Note that FE boundary conditions may still be overwritten by existing solid model boundary conditions if a subsequent boundary condition transfer occurs.)

SOLUTION:FEBodyLoads

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

Element to which body load applies. If ALL, apply to all selected elements [ESEL]. If ELEM = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for ELEM.

Valid body load label. Structural labels: TEMP (temperature), FLUE (fluence). Thermal labels: HGEN (heat generation rate). Magnetic labels: TEMP (temperature), JS (current densities), VLTG (voltage drop), MVDI (magnetic virtual displacements flag). Electric labels: TEMP (temperature), CHRGD (charge density). Valid labels are also listed for each element type in the ANSYS Element Reference under "Body Loads" in the input table.

Starting location for entering VAL data, below. For example, if STLOC=1, data input in the VAL1 field applies to the first element body load item available for the element type, VAL2 applies to the second element item, etc. If STLOC=5, data input in the VAL1 field applies to the fifth element item, etc. Defaults to 1.

For Lab=TEMP, FLUE, HGEN, and CHRGD, VAL1-4 represent body load values at the starting location and subsequent locations (usually nodes) in the element. VAL1 can also represent a table name for use with tabular boundary conditions. Enter only VAL1 for a uniform body load across the element. For non-uniform loads, the values must be input in the same order as shown in the input table for the element type. Values initially default to the BFUNIF value (except for CHRGD which defaults to zero). For subsequent specifications, a blank leaves a previously specified value unchanged; if the value was not previously specified, the default value as described in the elements manual is used.

For Lab=JS and STLOC=1, VAL1, VAL2, and VAL3 are the X, Y, and Z components of current density (in the element coordinate system), and VAL4 is the phase angle.

For Lab=VLTG and STLOC=1, VAL1 is the voltage drop and VAL2 is the phase angle.

When specifying a table, enclose the table name in percent signs (%), e.g., (BFE,ELEM,Lab,STLOC,%tabname%). Use the *DIM command to define a table.

Defines an element body force load (such as temperature in a structural analysis, heat generation rate in a thermal analysis, etc.). Body loads and element specific defaults are described for each element type in the ANSYS Elements Reference.

Notes

Allows repeated element body force loads to be replaced or ignored. Element body loads are applied with the BFE command. Issue the BFELIST command to list the element body loads. The operations occur when the next body loads are defined. For example, issuing the BFE command with a temperature value of 25 after a previous BFE command with a temperature value of 20 causes the new value of that temperature to be 25 with the replace operation, or 20 with the ignore operation. A scale factor is also available to multiply the next value before the replace operation. A scale factor of 2.0 with the previous "replace" example results in a temperature of 50. The scale factor is applied even if no previous values exist. Issue BFECUM,STAT to show the current label, operation, and scale factors.

Label (8 characters maximum, including the colon) for this block of BF commands on Fname2. This label is appended to the colon (:). Defaults to BFn, where n is the cumulative iteration number for the data set currently in the database.

Shell-to-solid submodeling key:

0 - Solid-to-solid or shell-to-shell submodel.

1 - Shell-to-solid submodel.

File Fname1 should contain a node list for which body forces are to be interpolated [NWRITE]. File Fname2 is created which contains interpolated body forces written as a block of nodal BF commands. Body forces are interpolated from elements having TEMP as a valid body force or degree of freedom, and only the label TEMP is written on the nodal BF commands. Interpolation is performed for all nodes on file Fname1 using the results data currently in the database. The block of BF commands begins with an identifying colon label command and ends with a /EOF command. The colon label command is of the form :Clab, where Clab is described above. Interpolation from multiple results sets can be performed by looping through the results file in a user-defined macro. Additional blocks can be appended to Fname2 by using KPOS and unique colon labels. A /INPUT command, with the appropriate colon label, may be used to read the block of commands.

SOLUTION:FEBodyLoads

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

Valid body load label. If ALL, use all appropriate labels. Structural labels: TEMP (temperature), FLUE (fluence). Thermal label: HGEN (heat generation rate). Magnetic labels: TEMP (temperature), JS (current densities), MVDI (magnetic virtual displacements flag). Electric label: TEMP (temperature), CHRGD (charge density).

Scale factor for the nodal body load values. Zero (or blank) defaults to 1.0. Use a small number for a zero scale factor. The scale factor is not applied to body load phase angles.

Base temperature for temperature difference. Used only with Lab=TEMP. Scale factor is applied to the temperature difference (T-TBASE) and then added to TBASE. T is the current temperature.

Scales body force loads in the database on the selected nodes. Issue the BFLIST command to list the nodal body loads. Solid model boundary conditions are not scaled by this command, but boundary conditions on the FE model are scaled. (Note that such scaled FE boundary conditions may still be overwritten by unscaled solid model boundary conditions if a subsequent boundary condition transfer occurs.)

Body loads are transferred from selected keypoints and lines to selected nodes and from selected areas and volumes to selected elements. The BFTRAN operation is also done if the SBCTRAN command is either explicitly issued or automatically issued upon initiation of the solution calculations [SOLVE].

SOLUTION:FEBodyLoads

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

Valid body load label. If ALL, use all appropriate labels. Structural labels: TEMP (temperature), FLUE (fluence). Thermal labels: HGEN (heat generation rate), TEMP (initial temperatures).

Uniform value associated with Lab item, or table name when specifying tabular boundary conditions. To specify a table, enclose the table name in percent signs (%), e.g., BFUNIF,Lab,%tabname%.

Notes

In a transient or nonlinear thermal analysis, the uniform temperature is used during the first iteration of a solution as follows: (a) as the starting nodal temperature (except where temperatures are explicitly specified [D, DK]), and (b) to evaluate temperature-dependent material properties. In a structural analysis, the uniform temperature is used as the default temperature for thermal strain calculations and material property evaluation (except where body load temperatures are specified [BF, BFE, BFK, LDREAD]). In other scalar field analyses, the uniform temperature is used for material property evaluation.

An alternate command, TUNIF, may be used to set the uniform temperature instead of BFUNIF,TEMP.

You can specify a table name only when using temperature (TEMP) and heat generation rate (HGEN) body load labels.

This command is also valid in PREP7.

Defines a body force load on a volume.

SOLUTION:SolidBodyLoads

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

Volume to which body load applies. If ALL, apply to all selected volumes [VSEL]. If VOLU = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for VOLU.

Valid body load label. Load labels are listed under "Body Loads" in the input table for each element type in the ANSYS Elements Reference. Structural labels: TEMP (temperature), FLUE (fluence). Thermal labels: HGEN (heat generation rate). Magnetic labels: TEMP (temperature), JS (current densities), VLTG (voltage drop). Electric labels: TEMP (temperature), CHRGD (charge density). FLOTRAN label: HGEN (heat generation rate).

Value associated with the Lab item or a table name for specifying tabular boundary conditions. Use only VAL1 for TEMP, FLUE, HGEN, and CHRGD. Use VAL1, VAL2, and VAL3 for the X, Y, and Z components of JS. For Lab=VLTG, VAL1 is the voltage drop and VAL2 is the phase angle. When specifying a table name, you must enclose the table name in percent signs (%), e.g., BFV,VOLU,Lab,%tabname%. Use the *DIM command to define a table.

Phase angle (degrees) associated with JS label.

Defines a body force load (such as temperature in a structural analysis, heat generation rate in a thermal analysis, etc.) on a volume. Body loads may be transferred from volumes to volume elements (or to nodes if volume elements do not exist) with the BFTRAN or SBCTRAN commands. Body loads default to the value specified on the BFUNIF command, if it was previously specified.

You can specify a table name only when using temperature (TEMP) and heat generation rate (HGEN) body load labels.

Body loads specified by the BFV command can conflict with other specified body loads. See Section 2.6.8.8 of the ANSYS Basic Analysis Procedures Guide for details.

Specifies "Biot-Savart options" as the subsequent status topic.

SOLUTION:Status

	Mp Me St DY LP Th E3 E2 FL PP ED

This is a status [STAT] topic command. Status topic commands are generated by the GUI and will appear in the log file (Jobname.LOG) if status is requested for some items under Utility Menu>List>Status. This command will be immediately followed by a STAT command, which will report the status for the specified topic.

If entered directly into the program, the STAT command should immediately follow this command.

Utility Menu >List >Status >Solution >Biot Savart Options

Calculates the Biot-Savart source magnetic field intensity.

SOLUTION:MiscLoads

	Mp Me St -- -- -- E3 E2 -- PP ED

Controls the Biot-Savart calculation:

NEW - Calculate the magnetic source field intensity (H_s) from the selected set of source elements to the selected set of nodes. Overwrite any existing H_s field values.

SUM - Calculate the H_s field from the selected set of source elements to the selected set of nodes. Accumulate with any existing H_s field values.

Notes

Calculates the Biot-Savart source magnetic field intensity (H_s) at the selected nodes from the selected source elements. The calculation is done at the time the BIOT command is issued. The units of H_s are as specified by the current EMUNIT command setting. Source elements include primitives described by element SOURC36, and coupled-field elements SOLID5, LINK68, SOLID69, and SOLID98. Current conduction elements do not have a solved-for current distribution from which to calculate a source field until after the first substep. Inclusion of a current conduction element H_s field will require a subsequent BIOT,SUM command (with SOURC36 elements unselected) and a SOLVE command.

This command is also valid in PREP7.

Specifies Boolean operation options.

PREP7:Booleans

	Mp Me St DY LP Th E3 E2 FL PP ED

Default/status key:

DEFA - Resets settings to default values.

STAT - Lists status of present settings.

Option to be controlled:

KEEP - Delete or keep input entity option.

NWARN - Warning message option.

VERSION - Boolean compatibility option.

Option settings if Lab=KEEP:

NO - Delete entities used as input with a Boolean operation (default). Entities will not be deleted if meshed or if attached to a higher entity.

YES - Keep input solid modeling entities.

Option settings if Lab=NWARN:

0 - A warning message will be produced if a Boolean operation has no effect (default).

1 - No warning or error messages will be generated if a Boolean operation has no effect.

-1 - An error message will be produced if a Boolean operation has no effect.

Option settings if Lab=VERSION:

RV52 - Activate the Revision 5.2 compatibility option (default). The 5.2 option can produce different numbering of the entities produced by boolean operations than the 5.1 option. See Notes below.

RV51 - Activate the Revision 5.1 compatibility option. The 5.1 option can produce different numbering of the entities produced by boolean operations than the 5.2 option. See Notes below.

Notes

Boolean operations at Revision 5.2 may produce a different number of entities than previous revisions of ANSYS. When running input files created at earlier revisions of ANSYS, match the boolean compatibility option (VERSION) to the revision originally used. For instance, if you are running Revision 5.2 and are reading an input file (/INPUT) created at Revision 5.1, it is recommended that you set VERSION to RV51 before reading the input.

See the ANSYS Modeling and Meshing Guide for further details on the functions of the RV51 and RV52 labels.

Generates a single line from a spline fit to a series of keypoints.

PREP7:Lines

	Mp Me St DY LP Th E3 E2 FL PP ED

Keypoints through which a spline is fit. At least two keypoints must be defined. If P1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI).

The following fields are used only if specified end slopes are desired; otherwise, zero curvature end slopes will be automatically calculated. The slope vector is parallel to a vector pointing from the origin of the active coordinate system [CSYS] to the position in space that XV,YV,ZV represents in that system.

Orientation point of an outward vector tangent to line at P1. Vector coordinate system has its origin at the keypoint. Coordinate interpretation corresponds to the active coordinate system type, i.e., X is R for cylindrical, etc. Defaults to zero curvature slope.

Orientation point of an outward vector tangent to a line at P6 (or the last keypoint specified if fewer than six specified). Defaults to zero curvature slope.

One line is generated between keypoint P1 and the last keypoint entered. The line will pass through each entered keypoint. Solid modeling in a toroidal coordinate system is not recommended.

Specifies the Boolean operation tolerances.

PREP7:Booleans

	Mp Me St DY LP Th E3 E2 FL PP ED

Point coincidence tolerance. Points within this distance to each other will be assumed to be coincident during Boolean operations. Loosening the tolerance will increase the run time and storage requirements, but will allow more Boolean intersections to succeed. Defaults to 1.0E-4.
