Hi everyone, i am performing a compressible VOF of a coaxial swirl injector using Ansys fluent, the boundary conditions are mass flux and pressure outlet at atmospheric pressure. using compressible air and incompressible water.
The problem I am facing is that during the initialization the velocity is not shown, and after 15-20 iterations it is getting diverted. I am using steady state, implicit formulation. with surface tension force modeling, K-e is realizable.
When it is running the console is showing Negative K in 500 cells.

Please respond if anyone can help me out with this.
