<div>Dear GMSHers,</div>
<div> </div>
<div>I am sorry. I am a bit confused.</div>
<div>When I read the GMSH manual, I get the feeling that I can only create groups on geometrical entities, not from mesh.</div>
<div> </div>
<div>Can I also create groups on a meshed structure?</div>
<div>(ie opening a nastran mesh for instance, selecting with the mouse some elements and assign them in a new group?)</div>
<div> </div>
<div>If so, how can I make sure that they are saved as a "Family" in MED format?</div>
<div>How may I choose to save this element set as "group" or as "family"?</div>
<div> </div>
<div>I thank you in advance for your help.</div>
<div>Best regards,</div>
<div> </div>
<div>Pierre</div>
