PNSInitialCondition
PNSInitialCondition
can be used to initialize variables by evaluating fluid properties for porous flow calculations. It can accept both interstitial and superficial velocities for initializing superficial or interstitial velocity variables and energy.
Example input file syntax
In this example, we initialize the first component of the superficial momentum with a specified superficial velocity. The superficial velocity is specified as a vector. We could have alternatively specified an interstitial velocity and the porosity.
