I am trying to simulate material removal in Comsol. My aim is that I want the material removal in the material after the temperature goes beyond its melting temperature. I have been trying to change density of the material as function of temperature but I am failing to do so. can anyone help me please to simulate this?

Hello,
i think the solution is to couple the deformed geometry solver with the heat equation solver. Similar problems are the removal of metal by electrochemical machining (look in the tutorial guide, there is an example "ECM microbore") or the electrochemical polishing. Both examples combine the deformed geometry with another physical phenomena to remove material. So maybe you can transfer the strategies to your case. Something like "moving mesh, when T>Tmelt" or something like his.
Good luck.
