I am developing a solver that gets a CAD model as entry and does the topological optimisation calculation on it. My solver is inspired by the open source codes presented in literature.
Since it is just a solver I need to do the pre-processing and post-processing using a third party code. I create my geometry and mesh using Abaqus and my solver retrieves the information in the .inp file in order to launch the calculation.
Currently the information that my solver retrieves are as follows:
The coordinate of the nodes, element types, Material type, B.C., etc.
I am wondering what the indespensable information are that any finite element code needs to retrieved from the CAD model and what are the information that are dependent on the type of calculation and can be ignored from one simulation to the other?
I hope my question is clear.

  • $\begingroup$ can you clarify, if you mean the information from the resultant mesh or the CAD model itself? $\endgroup$ – Anton Menshov Dec 9 '19 at 18:17
  • $\begingroup$ @AntonMenshov The information from the pre-processed model. The definition of a CAD model can be extended to : "a model representing the geometry, B.C., forces, mesh". $\endgroup$ – Dude Dec 11 '19 at 9:17
