Error : OpenCASCADE wire or line loop with tag 2 already exists Error : 'test_OCC.geo', line 390 : Could not add line loop
In the geo file there are several sections: Points Lines and Circles Line Loops and Surfaces Surface Loops and Volumes The numbering starts at 1 at the beginning of each of those sections. There is a Circle(2) and a Line Loop(2). Does the numbering have to be unique across all types of entities in OpenCASCADE? Von: Christophe Geuzaine [mailto:[email protected]] Gesendet: Dienstag, 19.

However, the crash for the more complicated one remains… Can I start gmsh with a parameter so that it writes error messages somewhere? I briefly that there are messages, but before I can open the message window, the application crashes. I forgot to say that I use Windows 7. Sure: just run on the command line : ./gmsh.exe file.geo - Matthias Von: Christophe Geuzaine [mailto:[email protected]] Gesendet: Dienstag, 19.

Unfortunately, it seems not to be that easy. It exports a step file now, but the geometry is not complete. I try it on a very simple geometry consisting of a three stacked boxes (see attachment). The upper one is missing in the step file. With the latest snapshot the exported brep seems correct: In my “real” geometry (which I cannot share), there were many Ruled Surfaces, causing gmsh to issue warnings since Ruled Surfaces seem to be deprecated. If I replace them by just Surfaces, gmsh crashes immediately when I open the geometry with the OpenCASCADE statement at the beginning. Can you try this more complex example with the latest snapshot?

Now I want to export it as .step for a colleague to view it in his CAD software. But gmsh complains “No OpenCASCADE model found” and refuses to write the step file. What can I do to fix that? Gmsh never translates between CAD kernels: so if you build your model with the built-in kernel, you won't be able to "export" it as as an OpenCASCADE model. What you could do is to add "SetFactory("OpenCASCADE")" at the beginning of your old script, and see if your geometry can get generated directly as an OpenCASCADE model. (You might have to change a few things.) Then you could export as .brep or .step.
