Hi Dr. Bergstrm and All my FEM mates,

I was not sure if it was the right place for this post.

Anyway, I am trying to model a poroelastic material deformation in Abaqus under a two phase loading 1-instantaneous (almost) pressure 2- constant pressure (which needs to provoke a poroelastic creep).

The point is, when I consider the model to be compressible (Neohookean), the permeability somehow shows its influence, but when the material is considered as incompressible, there could be found no trace of poroelastic influence. :confused:

of course, if I have done it correctly, I have let the fluid to flow freely in the boundary of the geometry (zero pore pressure BC).

Does this make any sense to you?

I am very grateful for your any comments,

Sincerely,
