Hello everybody,
I am new to this list and hope it is okay to start with a question.
I have already imported a *.stl file using the Merge option and am now
struggling to create a prismatic layer around it. As far as I now, it can be
done with the
Extrude{Surface{surface_number};Layers{{number_of_layers},{height_of_the_layer}};}
command. Therefore, I first have to define a surface on my stl-geometry in
order to refer to it. When I try to assign a elementary ruled surface, nothing
happens (I can’t even highlight a surface). When I try to assign a physical
surface, gmsh seems to accept it. At least the surface appears in the *.geo
file. When I want to extrude the newly created surface, gmsh complains about an
unknown surface 5.
My whole *.geo file looks like the following:
Merge „mygeometry.stl";
Physical Surface(5) = {2};
Extrude{Surface{5};Layers{{10},{0.5}};};
I would really appreciate any advice. Thanks a lot in advance,
Kate
