Divergence of multiphase turbulent flow in version 2021R1 but not in version 18.0

marijam · October 13, 2021, 13:08

Hello,

I am facing a strange problem while running a mixing tank in fluent version 2021R1.
It is a multiphase (air-water) system in a turbulent regime (Standard K-eps).
The same model in running in version 18 but diverges in version 2021.

Does anybody know what could be the problem?

Thanks,

It is quite possible, check the default values of the different variables, or even the default methods utilized.
