bfl

Mapdl.bfl(line='', lab='', val1='', val2='', val3='', val4='', **kwargs)

Defines a body force load on a line.

APDL Command: BFL

Parameters:

line

Line to which body load applies. If ALL, apply to all selected lines [LSEL]. A component name may also be substituted for Line.

lab

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. 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. When specifying a table name, you must enclose the table name in percent signs (%), e.g., BFL,Line,Lab,%tabname%. Use the *DIM command to define a table.

val4

If Lab = JS, VAL4 is the phase angle in degrees.

Notes

Defines a body force load (such as temperature in a structural analysis, heat generation rate in a thermal analysis, etc.) on a line. Body loads may be transferred from lines to line elements (or to nodes if line elements do not exist) with the BFTRAN or SBCTRAN commands.

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

Body loads specified by the BFL 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.
