Hi I am currently trying to model the indentation of various hydrogels using ABAQUS 2016.

I read the ABAQUS documentation and evnethough my model seems to be running I still cannot observe any relaxation or creep in my model.

The gel material properties I am using are (note that due to the size of my model I am using SI in mm, s, N)

** MATERIALS

**

*Material, name=Gel

*Elastic

0.26, 0.3

*Permeability, specific=1e-05

1e-07,0.

I

I provided a initial void ratio and set the pore pressure to zero on the appropriate edges so that fluid can flow out/in of the gel.

Any help will be very much appreciated.
