i am trying to simulate the weld pool procedure of laser welding, but some error happened when the model is computing. boundary temperature of domain is set as Tref+DeltaT, and “parametric” (auxiliary sweep) in the solver is used, DeltaT :1e2 1e3 2700 [K].
However, error happened when the DeltaT is 1.4e3 [K], and error message is "Failed to find a solution for all parameters,even when using the minimum parameter step.Segregated iteration leads to undefined function value.Returned solution is not converged."
Could u help me to solve this problem?
Thank u for your help.
