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:<br>

</div>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.).<br>
