importing CGAL generated mesh in medit format

Question

Since FEniCS CGAL interface is quite limited, I'm trying to generate 3d mesh using CGAL and then export this file to FEniCS.

The code is like this:

  std::ofstream medit_file("out.mesh");
  CGAL::output_to_medit(medit_file, c3t3);

I'm trying to use dolfin-convert on this file:

dolfin-convert out.mesh out.xml

I get the following error:
Converting from Medit format (.mesh) to DOLFIN XML format
*** Unable to find cell type.

Is there any way to export mesh data from CGAL to FEniCS?

Did you find a solution to this problem? I think the .mesh format which dolfin-convert is expecting is from "triangle" not from "CGAL".

I think you can fix it by editing the .mesh file. You need to put the Dimension on a separate line:

e.g. instead of "Dimension 3" change to "Dimension" (newline) "3" (newline)

Also, you may have to delete any triangles in the output. This is all a bit annoying and is really a bug in dolfin-convert.
