Residual thermal stress after laser ablation

Hello, I am a new in COMSOL, and I am trying to simulate the thermal stress changes caused by laser ablation. The ablation design has been completed, and it has produced reasonable results.
Currently, I am using solid mechanics and thermal expansion stress, but the stress values outputted are 0, and I am not sure where the setting might be wrong.
Additionally, I frequently encounter the following error during the simulation: "Failed to find a solution. Maximum number of Newton iterations reached. Linear solver error. Maximum number of intermediate iterations reached.
