I ran the model with a mesh size of 3mm (this is the lowest mesh size for the model to run in the Academic version of ansys) with a minimum step size of 100 and maximum of 200 (i.e. I applied a load of 33kN because I am modelling a 500MPa bar and it takes closely 60kN to reach yield and since I am only analying half of the model due to symmetry I did about half of this load). I am able to solve without an error and when I try to then converge on maximum principal stress (I saw you suggest this in one of the other threads), I get an error? Would you be able to know why this is the case? nI just want to plot a load-displacement curve to identify the slip between the rebar and concrete at yield stress and when the rebar fails.Hope you could give some guidance.n
