Hi Pierre-Frederic - This would actually not export the mesh, but the CAD model - so it's not what you want.

Indeed. I just had a look at the Abaqus documentation, and C2D3 and C1D2 do not seem to be in the general "Element Indexes" available in Abaqus/Standard. 

What should we use when we export "generic" elements (i.e., not linked to any physics)?

@Omid - any ideas?
