Dear all,

I tried to solve the liquid vapor multiphase problem using phase field equation under Fluent and couple it with navier stokes equation. However, my density is now a function of new scalar phi. If the density ratio is high, then my continuity converges poorly. Is there any way to deal with this? SOS!

thank you
