<div>Hello Paul</div>

<div class="">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).<br class="">
<br class="">
Where can I find the right format?<br class="">
<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>There are two formats. One (the legacy one) is self contained and is made of objects (triangles, tets, hexes) with datas. </div>
<div>There is no connectivity : every object is treated independently. See <a href="http://gmsh.info/doc/texinfo/gmsh.html#POS-ASCII-file-format" class="">http://gmsh.info/doc/texinfo/gmsh.html#POS-ASCII-file-format</a>.</div>
<div><br class="">
</div>
<div>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</div>
<div>that mesh. The doc is in <a href="http://gmsh.info/doc/texinfo/gmsh.html#MSH-ASCII-file-format" class="">http://gmsh.info/doc/texinfo/gmsh.html#MSH-ASCII-file-format</a>, see sections $NodeData, $ElementData</div>
<div class="">and $ElementNodeData.</div>
<div class=""><br class="">
</div>
<div><br class="">
</div>
<blockquote type="cite" class="">
<div class="">
<div class="">Is all the element supported (from shell to volumic elements - 1rst to 2nd order ones)?<br class="">
<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>Yes. High order elements are supported, in both formats.</div>
<div><br class="">
</div>
<br class="">
<blockquote type="cite" class="">
<div class="">
<div class="">Is there a limitation in terms of max number of elements?<br class="">
<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>No :-) The only limitation is the RAM of your computer. Note that the second format with $NodeData is clearly cheaper</div>
<div>in term of memory. </div>
