Description🔗
The pressurePermeableAlphaInletOutletVelocity
is a velocity inlet/outlet boundary
condition that can be applied to velocity boundaries for multiphase flows when
the pressure boundary condition is specified.
In this condition , an open condition is applied when alpha
is under a
user-defined alphaMin
value and a wall condition is applied when alpha
is larger than the alphaMin
.
This boundary condition can be used in conjunction with
prghPermeableAlphaTotalPressure
for the p_rgh
variable.
Usage🔗
The condition requires entries in both the boundary and field files.
