Hello Paras, Thanks for your response. I have been using the GUI of Gmsh to generate the mesh. Do you have any suggestions about what to do in Gmsh to avoid the negative volume issue?
Do meshes generated with Abaqus, are able to avoid the above-mentioned issue of negative volume? Thanks in advance.
