Adding heat flux and pressure at free surface
 

Hi experts,

I want to simulate a welding pool flow and surface deformation of arc welding, which is like a hair dryer blowing a piece of ice. But since the "air" here is actually "arc plasma", and I don't want to establish a MHD model.

So is it possible to use VOF model and melting/solidification model here and add heat flux and pressure distribution at free surface as "boundary conditions" of a melting pool by using UDF? How should I do it?

Thank you!
