Dear all,
please, ignore my previous message, I sent it unintentionally...
I have a problem converting my STEP geometry to .geo for use in gmsh. Steps
to reproduce:
- create a cylinder in FreeCAD and save it as a cylinder.step file
- load cylinder.step in gmsh, save it as cylinder.geo
- load cylinder.geo in gmsh - creating mesh fails with:
Info : Meshing 2D...
Info : Meshing surface 1 (Ruled surface, MeshAdapt)
Error : Unable to recover an edge 1.68237 -1.0812 && 2 -4.89859e-16
(10/10)
I should note that the following (without saving to .geo) works
- load cylinder.step in gmsh and create mesh - OK
but I would like to define the physical entities via GUI and I need geo
file to save them (if I understand correctly).
Please, can you advise me how to owercome this problem? I am quite new to
gmsh, so I may be missing something obvious...
remarks:
if I use .brep or .iges instead of .step, it fails with the same message.
If I replace the cylinder with a cube, there is no problem.
Thanks in advance,
Stepan Roucka
