I thought about introducing a moving heat source via DEFINE_SOURCE, however, we also have to apply drag forces on the liquid surface for our application. I got my own UDF for the heat source and applied it to the IJKL faces in the diagram above. It successfully ran as a heat source, but it seems to be the heat was not able to conduct to the workpiece. Is there anything I'm missing in this case? Besides, there are also some black spots on the surface which doesn't match with the UDF profile.
Many thanks!
