setfgap

Mapdl.setfgap(gap='', ropt='', pamb='', acf1='', acf2='', pref='', mfp='', **kwargs)

APDL Command: SETFGAP

Updates or defines the real constant table for squeeze film elements.

Parameters:

gap

Gap separation.

ropt

Real constant set option.

0 - Creates separate real constant sets for each selected element with the

specified real constant values (default).

1 - Updates existing real constant sets. The gap separation is updated from

displacement results in the database. Other real constants are updated as specified in the command input parameters.

pamb

Ambient pressure.

acf1, acf2

Accommodation factor 1 and 2.

pref

Reference pressure for mean free path.

mfp

Mean free path.

Notes

This command is used for large signal cases to update the gap separation real constant on a per-element basis. Issue this command prior to solution using the default ROPT value to initialize real constant sets for every fluid element. After a solution, you can re- issue the command to update the real constant set for a subsequent analysis. See Introduction for more information on thin film analyses.
