Re: How is smesh (salome mesh) module maintained in FreeCAD
I also got segment fault, if our research project will use netgen later, I may have time to investigate. for the time being, I may leave it as it is. There is patch for netgen 6.2, not sure how good it is. netgen license is GNU Lesser General Public License v2.1. it is compatible with FC, an easy wa...

Re: How is smesh (salome mesh) module maintained in FreeCAD
Good to hear this. I gave up on latest netgen and settled at 6.2.1808. But this also needs some patches to work. netgen 6.2 has been developed for 3 years, lots of change. If you mean patch is needed to work (not only to compiling), then I'd better to give up. I just use netgen in ubuntu (it may be...

I have updated salomemesh from 7.7 to 8.3, tetgen 6.2 has change that break smesh code in freecad. like excpetion and pybind11 macro, I fixed it by 2 latest commits. https://github.com/qingfengxia/SMESH further discussion on smesh is in another thread. https://forum.freecadweb.org/viewtopic.php?p=34...

Re: How is smesh (salome mesh) module maintained in FreeCAD
I split out salome geometry module, it is now on github https://github.com/ukaea/SGeom I managed to compiled smesh 8.3 with latest FreeCAD without netgen. Freecad test workbench does not complain any error. I will send a PR , can someone have a test on other platforms, windows. This smesh may not wo...
