Hi all,
I am modeling a high-velocity (200 m/s) flow of water vertically entering the air. The water is supposed to hit the wall after traveling a 0.5 mm distance. The flow is highly turbulent, and I am using the k-omega phase-field approach for modeling.
The problem is that once the jet approaches the wall, the problem stops converging (Error: maximum number of segregated iterations reached). Any idea what is the root of the problem and how to solve it?
Thank you for your time in advance,
Majid

The following points may help you,
this is happen because the Gaussian equation is not fulfilled properly.
(1) you can increase the number of cycles (1000) SCF=maxcy 1000
(2) using the quadratically convergent method
(3) use fine meshing at starting of your geometry. at highlighter points of investigation
Unsteady flow normally have no sense to speak about convergence. May be need more improvement on mesh and use others linear solvers more suitable for such problem
