Hi all. I'm trying to set up an example in PreView that's sort of like the micropipette aspiration of a chondrocyte. I made a sphere (cell) and a cylinder(pipette) , made the cylinder rigid, and defined a contact interface between them. I was uncertain of whether to prescribe a negative pressure to the surface of the cell, a nodal load, a prescribed nodal displacement, etc. to model aspiration, but that's a different issue. Regardless of the method I use, I get errors about negative Jacobians and bad node numbering. Originally I built the geometry in PreView and let the program generate the meshes, but then I tried importing it from external software (Salome => GMsh => PreView) and had the same problem. I've attached my .prv and .feb files. I added a few nodes in PreView to set certain boundary conditions but everything else was done externally. Thanks in advance!
