Weld surface deformation by VOF model
I am trying to track the weld surface deformation with the help of VOF model. I am considering a 3D transient model where laser beam is striking on the metal surface as heat source. I have written a UDF for this heat source. It works well. For melting the surface, solidification/melting model has been incorporated. Now I would like to track the VOF model. But I am confused how the computational domain should look like for VOF model? For tracking surface deformation, do I need to write any udf for surface tension/forces? In my model, I am not considering key hole. Any advice will be highly appreciated.
