How to use dolfin-convert in Python API?

0 votes

I would like to use a mesh generated with Gmsh (with extension .msh) in DOLFIN, and after a bit of research I found I should (could) use the built in dolfin-convert prompt to convert it into a .xml file, but nowhere seemed to find how to carry this out exactly. Any help is appreciated.

(Working on a Mac, FEniCS in Python API from Terminal)

closed with the note: worked it out, there was no need to enter the system-python to begin with
