Hi!

Is there a way to bound the maximal k, epsilon and omega values in openfoam without recompiling a new solver (due to my lack in programming knowledge)? I would think openfoam has this already built-in as it is a common thing to do (perhaps one can define it in a dictionary like RASProperties or fvSchemes?).

Thanks,
Matej

Hi,

Take a look at User Guide - 4.4.1.1 Schemes for strictly bounded scalar fields, http://cfd.direct/openfoam/user-guid...20-1080004.4.1.

Unfortunately in RASProperties you can set only lower limit for k, epsilon, and omega.

Also you can try (though you have mentioned lack of programming skills) to use temperatureLimitConstraint fvOption as a base for turbulentFieldsLimitConstraint fvOption.
