How to remove the fiction on the interface in interFoam?
 

Hi everyone,

The problem I confront when I use interFoam is: the velocity of the gas phase is much too big so the timestep has to be very small (to keep courant number <1), that wastes me a lot of time. In fact, gas phase has little influence on the simulation. So can anyone tell me how to remove the fiction on the interface?

Best wishes!
