I am trying to simulate laser welding of two dissimilar materials. During this, a heat source model is to be implemented. The model needs to be simulated in a coupled model of thermal-mechanical as well as fluid. The two dissimilar will fuse together when the materials reach the melting or fuse temperature. I want to simulate this fusion of the two materials. How can I implement this using APDL. Please help me with this.
With best regards.
