I am new to Gmsh and I would like to make a 3d thetrahedra solid mesh for calculix stress calculations. It is a periodic slice of a 3d radial turbine model.
I think I need to input the *nodes*, not the elements that have faces on a given surface, say, periodic suction side surface, to Calculix to fix boundary conditions. If I write out the mesh in ABQUS format and name a plane in the geometry, physical group, then I get the elements who have faces on the surface. I also saw this: http://onelab.info/pipermail/gmsh/2013/008643.html Can you please help me to clarify this: Calculix needs the nodes lying on the surface? Am I right? How do I persuade GMSH to write this? Thank you so very much for reading! Best regards, Zuheyr -- Zuheyr Alsalihi
