Biphasic model w/poroelasticity: Abaqus/CAE problem
Biphasic model w/poroelasticity: Abaqus/CAE problem
(OP)
Hi everyone,
I'm having a problem with implementing the 'Porous Elastic' material model in Abaqus/CAE 6.9 (I've the student edition).
The problem I'm trying to solve is an indentation of a deformable (biphasic) slab by a rigid, spherical indentor. When I define the slab as poroelastic, I seem to get an error
'THIS KEYWORD IS NOT AVAILABLE IN Abaqus/Explicit'
and the job terminates. However, the same model executes perfectly fine if I use a different material type (say, hyperelastic). I'm not sure if it's because of the data values I've specified for the poroelastic material; or because my strains are too high, or if there's something else.
Would really appreciate any hints/suggestions on this.
Thanks!

'THIS KEYWORD IS NOT AVAILABLE IN Abaqus/Explicit'
The *POROUS ELASTIC keyword is only available in Abaqus/Standard (Abaqus analysis user's manual 18.3.1)

I half figured that out late last night, after which had a pain of a time figuring out how I go implicit instead of explicit (stupid, I know, but I'm new to Abaqus). Things running fine now. Thanks again!
