Hi Ashish, Thank you for the reply.  Yes, it converged without creep.  I attached more information about the model below.  I turned on the creep function after step 1.  The convergent issue only occurred when creep is turned on.  What would you check in the next step?

Material properties:

Anisotropic elasticity:

Anisotropic CTE:


Boundary conditions:

Temperature loading:

Time step setting for step 2 and 3:
