I am doing structural analysis of a quarter spherical particle. I am imposing the Temperature field T(x,t) by importing a "text file" as interpolation. These temperature values are function of position of particle and time.
The objective is to run the elastic-plastic analysis along with creep function. I expect to have relaxation of stresses while using creep function (Rather than using only Elastic-Plastic analysis). As creep is time dependent function, therefore, I am using Time-Dependent study.
However, I am getting this error "Convergence problem in time dependent solver...last time step is not converged, Nonlinear solver did not converge"
Please help me in this regard, this is very crucial for my research.
I can attach my model, if needed.
Thanks
