# 7.16.1.14.7. Static_Porous_Term

Syntax

  Source For Cvfem Momentum [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {@ | at | for | on | over} MeshPartIdentifier = Static_Porous_Term

Summary

  Source Term required when material flow is coupled with porous fluid flow. The term is needed when the gas phase pressure can effect the motion of the matrix phase With out this term, at a constant pressure with a porosity gradient there will be motion of the matrix phase.
