Hi!
I am trying to simulated a gas stirred vessel (metallurgical ladle) using Eulerian multiphase model in 2D axisymmetric geometry. I´m using explicit scheme and dispersed turbulence model. The problem is that the solution diverges, showing an Courant number very high and also (sometimes) a flotating point error. I have used different mesh size using 7000, 12000, 17000, 24000, 50000, 100000 and 400000 elements, time step since 1e-05 to 1e-08 but the divergence still appears. What could be the cause? Please, if have any suggestions, I will apreciate it.
The mesh is very fine in the simmetry axis and the interface of liquid.
Thank you.
