Optional parameters
-
AMPLITUDE
-
Set this parameter equal to the name of the amplitude curve defining a
multiplier for the fluid exchange magnitude. See Amplitude Curves.
-
BLOCKAGE
-
Set
BLOCKAGE=YES
to consider vent and leakage area obstruction by contacted surfaces. The
default value is
BLOCKAGE=NO.
-
DELTA LEAKAGE AREA
-
Set this parameter equal to the ratio of the actual surface area over the
initial surface area at which you want the fluid to leak. This real
value should be positive and greater than or equal to one. The effective
surface area used for the fluid exchange is the difference between the
actual area of the surface and the area of the surface at the beginning
of step.
-
OP
-
Set
OP=MOD
(default) for existing FLUID EXCHANGE ACTIVATION
definitions to remain, with this option defining a fluid exchange
activation to be added or modified.
Set
OP=NEW
if all fluid exchange activations that are currently in effect should be
removed. To remove only selected fluid exchange activations, use
OP=NEW
and respecify all fluid exchange activations that are to be
retained.
-
OUTFLOW ONLY
-
Include this parameter if the flow is allowed only from the first fluid
cavity to the second fluid cavity defined in the FLUID EXCHANGE
option.
If this parameter is omitted, the flow is allowed from both directions.
The reference nodes defined on the data line on the FLUID EXCHANGE
option should be in the appropriate order to obtain the desired flow
direction.
