Hello Freinds,
I want to develop a two-temperature model for ultrashort laser ablation. The first laser gives the energy to the electron and that electron heated up. Now, this electron gives its energy to the ion grid and relaxes quickly. I want to build this model in COMSOl.
Right now, I am using a 2D axial symmetric model and also coupled two governing equations to find the electron temperature and ion grid temperature in COMSOL. But I don't know how to solve this coupled PDE because of the high nonlinearity? If anyone already developed two temperature model then please let me know about the Dirichlet boundary condition?
