    Locking in poroelasticity

    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 Andre

    Locking in poroelasticity

    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. Andre

    Locking in poroelasticity

    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

    Poroelastic material with low permeability in ABAQUS

    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...

    Node sets after volume mesh generation

    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...
