<p style="margin: 0px;"><span style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:#000000;text-decoration:none">I want to show my group at my working place, that the combination of gmsh and getdp is at least as powerful as an commercial FEA Software or even more powerful. For that purpose I have imported a model of an Claw Pole Alternator as a step file into gmsh. That worked very well and it is no problem to pick the faces and volumes with the gui. But because of the fact that I have imported the geometry I have no information about the elementary entities in the geo file. So I can't change the characteristic lengths individually for the interesting lines/points. </span></p>

<p style="margin: 0px;"><span style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:#000000;text-decoration:none"> Is it possible to get for example the volume or a surface with a command like 'get volume at point (x,y,z)' ? That would be awesome to automate the picking of the areas and volumes for defining the physical entities. </span></p>

<p style="margin: 0px;"><span style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:#000000;text-decoration:none">Is there a function / command to get the surfaces that define a volume or the lines that define an area? The problem is that the geometry is very complicated and I need to define the elements for every volume or area seperately to get a fine mesh in the airgap and a coarse mesh in the outer air and so on. </span></p>
