I am imposing the very high temperature field i.e. T(r,z) on 2D axis-symmetric (cylinder) model in order to calculate stresses/strains. As temperature is high enough to yield the material , so I am expecting plastic strain.
Surprisingly, If I use only symmetry boundary conditions (on center and bottom edge) there is no plastic strains!
If, I try to constrain the bottom edge, it causes a large error and convergence issues.
Any suggestion please. I wondering why symmetry boundary conditions are causing no plastic strains!
Thanks,
