A.Jalal is on a distinguished road
All,

I am trying to simulate a valve closing in ANSYS Fluent 16.2 and would like to create a UDF that allows me to specify a zone as a porous medium once two walls get very close to each other that way fluid will still pass through without recieving any negative volume errors.

Doe anyone have any suggestions. I am basically modelling a 2D plane of a valve body and a spring loaded poppet.

Thank you
