Culling nodes

Post by eranalli »

I'm trying to use FreeCad to predict the deflection of mirror surfaces due to loading.
After performing an FEM analysis (using CalculiX) how can you get a listing of node positions and associated offsets/stresses/etc, which correspond to a surface? That is, how can you filter the nodes you care about on a particular surface from those spanning the whole volume?
I'm using FreeCad 0.18
Thanks!

Thanks!
If I understand things correctly, I can fit a best-fit plane or sphere as an implicit function cut. I'll play around with that. I think this is promising.
