I used C3D10MP in the pictured model. I made a hex mesh with C3D8P elements, that apparently solve the problem. Though hex meshes are very hard to develop in organic geometries, so I would like to have a solution that involves tet elements.
Thanks

Jay,
Thanks for your reply.
A considerably finer mesh will still exhibit those problems and I can't afford to refine it further. Using a hexahedral mesh seems to solve it, but it is not the desirable solution either.

Dear all,
I am having problems with my low-permeability model in ABAQUS using tetrahedrons C3D10MP.
A resulting pore pressure with a checker-board-ish pattern appears.
Is there a way of tackling this permeability locking?
Best,
Andre
Dear all,
I am trying to develop a poroelastic model of bone, and the intrinsic permeability values are very low (10^-24 m^2). I'm having a problem when going from higher permeability material properties to lower permeability.
The obtained pore pressure distribution results in a weird pattern...
I am applying the tool "tri to tet" in a quadratic element mesh.
Before that, the nodes are sorted by their label in the structure mdb.models[NameOfTheModel].parts[NameOfThePart].nodes
After applying it, the mid-edge nodes keep the same label, but change position in the structures.
For...
