Dear Gmsh development team,I have recently switched to Gmsh for generating my meshes for hybrid finite element-discrete element analyses. I was using Cubit (Sandia Labs) in the past, but I have been impressed by how easily graded meshing can be achieved in Gmsh, hence the switch.
I need to export the meshes generated in Gmsh to the Abaqus .inp format. Everything works fine for exporting the finite elements and I can easily group them by assigning "Physical Entities" ("Element Set" in Abaqus lingo). However, grouping the mesh nodes into "Node Sets" seems a bit tricky since apparently all Gmsh Physical Entities are exported as different types of Elements in the inp file. I've attached a standard Abaqus inp file to this email, which contains 2 Element sets (ELSET=EB1, EB2) and 3 Node Sets (NSET = NS1, 2, 3). I am wondering, is it possible to change the code for the Abaqus export to follow the above syntax, which more clearly separates elements and nodes? If you can also direct me to the right place in the Gmsh source code, I can perhaps do it myself and contribute the code. (I've seen writeabaqus.cpp but I don't know how to start.)
I would appreciate your prompt help and guidance in this matter. Best regards, Omid Mahabadi -- Omid Mahabadi Geomechanica, Inc. Tel: (647) 478-9767 x824
