Hi,
I am working on multi-phase flow in porous media using ANSYS-CFX. In this kind of problems, porous domain might change in thickness because of external pressure. My main problem is I can not model this king of compaction in my transient simulation.

1- Do I need an external solver for this problem?
2- Compaction can be modeled as a function of pressure and other parameters. Is it possible to get a real-time observation of this parameters and use this compaction models to update domain thickness during run?

Does any body have Ideas about this issue?
Thanks
