Dear Pierre,
Unfortunately, I do not have access to Abaqus now so I cannot really
test anything. You may want to directly post on the Abaqus forum.
Good luck,
Omid

Dear Christophe and Omid,
The SVN r15421 did solve partially my problem. I manage to import the
mesh in Abaqus/CAE 6.12. "Physical" elements are nicely recognized as
Assembly's Sets, even with their name.
However, I cannot use them to apply boundary conditions. Do you know
where the problem comes from or should I try to directly post on
Abaqus forum?
.geo and .inp files are attached.
Thank you very much for the help.
Best wishes,
Pierre

is that there are so many different element types in Abaqus that
makes defining a "generic" type rather impossible. I would suggest
to keep the default Abaqus export as currently is, but give the
user the option to define custom types in the gmsh geometry file.
For instance, in the case of a 2D mesh, the user may define a
maximum of two strings for the 1D and 2D element types, which can
look like:

With SVN r15202 I at least changed the default tags to tags that
should be understood by Abaqus/Standard (had to change lines,
triangles and quads). We might want more flexibility in the
future, but it might also be overkill (we need types for 1st order
and 2nd order elements, etc.).
