I want to simulate a metal injection molding process using CFX.In this situation , we mix the metal powder(solid particle) with the binder(continuous liquid) together,usually the metal powder have a high volume farction(50%-75%).we set the injection velocity 10m/s and temperature 400k.which model should i use? solid particle collision models? How can i monitor the filling process, i mean how to determine is it full filled or not? thanks!
