Hi Sir,

I have checked the VOF model and also tried multiple settings in the viscous tab, BC, or initialization, but the issue of "turbulent viscosity & temperature limited to 5.000000e+03" still persists. 

Currently, after setting everything, I have turned off all the equations. First, I converged the flow, and then I turned on the Energy to make it converge as well, but the simulation diverges after a few iterations. It seems that the multiphase is not the problem, but the energy equation is the problem. 

I have used multiple mesh size but I don't understand what is the real reason. can reverse flow also lead to this temperature limitation or turbulent viscosity warning?
