Hi Jean-François,

Thanks for the information's ; even if post-processing is a part of gmsh capabilities, I've been looking for a "light" but accurate post-processor to share results with my colleagues : gmsh is fully adapted for that purpose

"Y'a plus qu'à "

Thanks

Paul

Hi All

Hello Paul

I'm thinking in interfacing a FEA code to Gmsh for post-processing
results ; for that topic the documentation is speaking about an old
file format (legacy).

Where can I find the right format?

There are two formats. One (the legacy one) is self contained and is
made of objects (triangles, tets, hexes) with datas.
There is no connectivity : every object is treated independently. See
http://gmsh.info/doc/texinfo/gmsh.html#POS-ASCII-file-format.

The second format is more standard. You have to have a mesh (i.e. a
connectivity) and FE results can be saved as data’s for
that mesh. The doc is in
http://gmsh.info/doc/texinfo/gmsh.html#MSH-ASCII-file-format, see
sections $NodeData, $ElementData
and $ElementNodeData.

Is all the element supported (from shell to volumic elements - 1rst
to 2nd order ones)?

Yes. High order elements are supported, in both formats.

Is there a limitation in terms of max number of elements?

No :-) The only limitation is the RAM of your computer. Note that the
second format with $NodeData is clearly cheaper
in term of memory.

Thanks for any feedback

Regards

Paul
