Default turbulent dissipation rate

hi guys,

i am modelling a multiphase flow and when i begin my simulation i am getting a floating point error. the problem appears to be the turbulent dissipation rate (tdr) because as the residuals start the tdr graph continues to increase and does not converge. I've increased the tdr and turbulent kinetic rate (tkr) values and i no longer receive a floating point error. Can somebody please help me in choosing a suitable value for these two rates. the multiphase flow is air and water

thanks for the help

Are you working with dof model or steady?

Do you have the "Cell Quality Remediation" activated in your physics? If you have then you may want to check your initialization.

I apologize for the late response. The model is steady. Yes, I have enable cell remediation in the physics model

Thanks for the assistance
