<br>
I have several partial meshes in med-format. Is there a way with GMSH to<br>
assemble them to the complete mesh (similar to CODE_ASTER's command<br>
ASSE_MAILLAGE)??<br>
<br>
I tried:<br>
<br>
gmsh part1.med part2.med part3.med<br>
<br>
which seems me the same as doing<br>
<br>
gmsh<br>
<br>
and then: Menu - File - Merge.. or: Menu - File - Open..<br>
<br>
The effect is that I have several models in gmsh which I can switch<br>
between using the button at the very bottom left. But they are not<br>
really merged, I need to export ONE .med-file containing the union of<br>
all parts<br>
<br>
(2)<br>
<br>
what is the difference between<br>
<br>
Menu - File - Merge..<br>
<br>
and<br>
<br>
Menu - File - Open..<br>
<br>
many thanks for your help,<br>
<br>
Regards<br>
Johannes_ACKVA<br>
