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