I am trying to implement solution model similar to laser welding process as Mr. M.Courtois et al describes in the paper "A new approach to compute multi-reflections of laser beam in a keyjole for heat transfer and fluid flow modelling in laser welding". Electrimagnetic waves interface is stationary and oher interfaces are transient, as shown on the picture. How is it technically possible to couple solwers in that way so steady-state solver invokes on every time step of separate transient solver? I spent much time searching bun have not found straightforward answer.

Hello, I am a novice in welding. I have built the solidification and melting model according to my paper, but I have been reporting mistakes. Could you please help me?
Sincerely
