Hello all,

As a part of my master thesis

I am trying to simulate Steel-Argon flows (steel continuous phase and argon discrete phase) with free surface and the simulation is not stable.

I have limited the courant number to 0.85, after few iterations very small time steps will be used (of the order 1e-06) and simulation crashes with high courant number.

Before this I tried water (continous)-air(discrete) simulation with the same grid, inital conditons and boundary conditions.
But now whe n I change the density of the continous phase from 1000 to 7000 (Steel density) simulation crashes.

Do I need to change the coefficients of Cvm, Cl and Ct in constant/transportProperties ?

awaiting for your suggestions

Regards
Raghavendra
