[Getdp] questions concerning parametrisation

[Masi Koskinen]

Hello,

I'm a postgraduate student working at the institute of  
electromagnetics (TUT). My current modelling task concerns creating a  
3d-model of an inductor. I'm quite new to gmsh and getdp, so I have a  
couple of questions. So far I have only used commercial softwares like  
SolidWorks and FEMLAB but now my tutor Saku Suuriniemi is encouraging  
me to acquint myself with gmsh and getdp.

The first challenge I've encountered is how to model the core of the  
inductor so that it is easy to modify and without ending up writing  
dozens of unnecessary lines. The core of the inductor is made of  
identical pieces of iron separated with plastic disks that have the  
same cross-sectional surface as the pieces of iron but varying  
thickness. What would be the easiest way to parametrise such a  
structure? Should I form the cross-section area once and extrude all  
the pieces using it?

My second question concerns creating a model for getdp in general. Is  
it possible to create pieces of a model in separate files and assemble  
them in one main file? How does the numbering of points, lines etc. go  
in that case?


Cheers,
