phase change of powder-liquid-solide

Please login with a confirmed email address before reporting spam

Hello everyone! I'm trying to model the laser melting in the additive manufacturing which means I must have the correct phase change in the system. I want to model phase change of powder-liquid-solid that has three phase but the phase-change module in COMSOL only can realize phase1 to phase2. In addition, when powder change to liquid it will never change back to powder again but change to a solide phase. How can I do that using COMSOL?

I will be glad with your answers!
