Default Two phase flow with phase change

Dear all,

I am simulating two phase flow (Liquid water and vapor) with phase change. I would like to generate superheated steam from sub-cooled liquid. I am using continuous continuous Euler Euler inhomogeneous model. I am facing convergence problems and the mass and energy imbalance are very large. Any help is welcome.

Regards

Ahmad

For convergence , set the lower values in Expert parameter >> Convergence control >> Relaxation parameters 0.25 will give you very good mas convergence. -mohan
