TETGEN

[pg1988]

Hello,
I want to use tetgen for re-meshing part of a cube. This is the first time I am using this software. I have already executed the C++ code given in the manual and it works fine. Now, I wish to re-mesh a part of a cube but I am confused as to how should I start the code or how should I pick certain faces/edges to be re-meshed. Any help would be appreciated.
Thanks
PG

Hi
Did you mean Netgen

or do you really mean Tetgen?

FreeCAD uses the salome smesh library for volume meshing. You find the code in freecad's 3rd party folder https://github.com/FreeCAD/FreeCAD_sf_m ... alomesmesh
You could have a look at the netgen plugin and how it works and then create such a plugin for tetgen. than it could be easily integrated into freecad.

To see how smesh it is integrated into freecad you need to dig through the fem workbench, I never studied the code for it so I don't know it.

As far as I know it smesh is also used from within the mesh workbench for surface meshing. You could also look there how a possible tetgen plugin could be integrated.

Tetgen is under (A)GPL and there fore not usably to FreeCAD...
