A solution is contained at the getDP wiki page, see http://geuz.org/getdp, e.g. the electrostatics example Capacitor2D: 

Here names of physical objects, appearing under Gmsh's GUI tools/visibility/physical - list are defined in an extra parameter.pro file like 

	LPLUS=100;

with an 

	Include "parameters.pro"; 

statement in platehole.geo as well as in platehole.pro. 

The names are synonymes to the numbers of the physical objects defined in platehole.geo, as  

	Physical Line(LPLUS) = {22};

and are used in platehole.pro's group definition too, e.g.

	Lplus= #LPLUS;

The parameter file allows also sharing model dimensions in Gmsh and getDP. 

I can add to Ingos list: 

7.) I used a buggy for-loop with an erroneous "matching" end statement 

	For i In {0:n} ... ; EndIf

without any error in the Gmsh message console (no If or other EndFor was present in the geo file) and was searching quite a while what's wrong there. Would it be possible to add some more syntax checks in the future Gmsh version? 

Nice greetings from Vienna, 

Karl
