Re: [Gmsh] Gaps and overlaps when using extrude command

I am not sure because I seldom use the GUI. But what I am pretty sure of is that Gmsh works the way it should. It would help to know what the actual errors you get are. -- jeremy theler www.seamplex.com On Sat, Aug 15, 2020, 07:25 Bart Deschoolmeester < bart.deschoolmees...@bbri.be>

Re: [Gmsh] Small element size factor does not work

RT(F)M, section F.5 question 3 in http://gmsh.info/doc/texinfo/gmsh.html#Mesh-module-questions How can I only save tetrahedral elements (not triangles and lines)? By default, if physical groups are defined, the output mesh only contains those elements that belong to physical entities. So to save

Re: [Gmsh] Gaps and overlaps when using extrude command
