SETFGAP

SETFGAP, GAP, ROPT, --, PAMB, ACF1, ACF2, PREF, MFP
Updates or defines the real constant table for squeeze film elements.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

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.

--

Unused field

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.
