Moving mesh method to simulate laser material interaction

Please login with a confirmed email address before reporting spam

Hello,

I am working on the laser material interaction using moving mesh method. I want to study the effects of recoil pressure and other forces (normal and tangential surface forces ) acting on the surface of molten liquid formed due to laser heating. I have attached my model for your reference. It does not execute properly. am trying to simulate similar to the given link which is a paper submitted in comsol conference 2015 in Pune. I have attached my model file for your reference.

As reported in many works, I am considering only liquid material in the single domain which can be made to acts as solid by changing its viscosity to 100 Pa.s below the melting point. However, it is not converging and not even moving the liquid interface. I appreciate any help on this.
