- Mapdl.bfv(volu='', lab='', val1='', val2='', val3='', phase='', **kwargs)¶
Defines a body force load on a volume.
APDL Command: BFV
Volume to which body load applies. If ALL, apply to all selected volumes [VSEL]. 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 Element Reference.
- val1, val2, val3
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 = JS in magnetics, use VAL1, VAL2, and VAL3 for the X, Y, and Z components. For acoustics, if Lab = JS, use VAL1 for mass source in a harmonic analysis or mass source rate in a transient analysis, and ignoreVAL2 and VAL3. 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
*DIMcommand to define a table.
Phase angle in degrees associated with the 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 Resolution of Conflicting Body Load Specifications in the Basic Analysis Guide for details.
Graphical picking is available only via the listed menu paths.
This command is also valid in PREP7.
Set heat generation 1e4 on all selected volumes.
