Re: Gmsh generates a mesh with 0 nodes 0 edges 0 faces...

I can make a 2D mesh with FreeCAD but no a 3D one or a "From Shape".

Re: Gmsh generates a mesh with 0 nodes 0 edges 0 faces...

I've done what you said in two ways: 1) Starting gmsh thu linux menu and openning the brep file: trying a '3D' mesh, gsmh stalls. 2) Starting gmsh thu command line: gmsh crashes with the following error: ~$ /usr/bin/gmsh /tmp/Box_Geometry.brep Delaunizing vertices... Delaunay seconds: 0.002583 Creat...

Strange ... Would you check your gmsh installation as follows ... Are you able to run gmsh on the shell, with the commands provided at the end of the geo file? Does gmsh create a unv mesh file?
No unv mesh file created.

Re: Gmsh generates a mesh with 0 nodes 0 edges 0 faces...

Hi, thak you for your efforts. I've tried the simple way you've just recommended. No mesh. freecad gmsh problem.png I've attached several files: -Screenshot where you can see the generated mesh and 0 nodes 0 edges... -FCStd file -.brep and .geo files in case they may help (geo file is renamed adding...

Re: Gmsh generates a mesh with 0 nodes 0 edges 0 faces...

I'm trying to do it again but gmsh spends more and more time... it looks like gmsh is busy or too slow.

Re: Gmsh generates a mesh with 0 nodes 0 edges 0 faces...

The steps are the following: 1) On Part, create a box solid 10x10x10, 2) On FEM, create Analysis, 3) select material (wood-generic in this case), 4) select fixed constraint on one face, 5) select constrainst force on another face, 6) select the box and "create a FEM mesh from a shape by gmsh mesher"...
