Many thanks for the suggestion.
What I noticed is that at most of the cells in the domain, the epsilon is close to the minimum value of 2.2e-16, and the calculated k (from R) is close to the...

Thanks for the suggestion. I am looking forward to use it. Do you feel I need to include the source term of epsilon in fvOptions too?

I have not used fvOptions file (in constant directory) in my simulations. Could you please give some example/reference of a fvOptions file to limit the velocity?

Thanks. I tried several fvSchemes to limit the alpha between 0 and 1, but still some -ve values are there which is possibly generating the -ve epsilon. The problem is starting with bounding epsilon...

Many thanks for your valuable comment Tobi. I have used relaxation of 1 for the above-mentioned terms. The fvSolution and fvSchemes are:

Bounding epsilon error while running LRR/SSG using interFoam

Hello to every one,

I am trying to simulate supercritical multiphase flow (interFoam) using different RAS models to get the best solution. The simulation is running with k-e, RNG, k-wSST etc., but...
