[Gmsh] Some bug?

[David Colignon]

Hi,

it's not a bug, just a new feature in the 2.0 version : the extrusion syntax has changed (see http://www.geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC36 ) and explicit region number specification in extrusions has been removed.

Extrude Surface {18, {0,0,-T}} { Recombine; Layers { {nT}, {T} }; };

becomes 
 
Extrude { 0, 0, -T } { Surface {18 } ; Layers { {nT}, {T} }; Recombine;} ;

Then you can use the Visibility window to check the numbers of the created volumes ( Physical Volume(101) = {1,2,3}; ), or use a variable to store them, as I did in the attached .geo file.

Cheers,

Dave
