Workflow for FEniCS

Hi all,

I would like to know if anyone has any experience or pointers on how to use Cubit to mesh a geometry, tag subdomains and use it in a FEniCS script.

I was unsuccessful with meshio so far and was curious to know if someone tried to do something similar.

Thanks in advance!

Hi @remdelaportemathurin

That’s the troublesome part. I am not quite sure which mesh types fenics supports yet. I only know of their native XDMF format and that there should be a reader for gmsh .msh files. But Cubit doesn’t support any of those.

There are 3 options:
• use a converter like meshio to convert a mesh from lets say abaqus to dolfin
• if you are aware of the right syntax, you can write yourself an exporter with the cubit sdk
• code a new reader for fenics to import other mesh formats
