Default Scaling the Reynolds stresses via UDF
Posts: n/a

I want to multiply the computed Reynolds stresses in the momentum equation by a certain value (scaling of the Reynolds stresses). My first idea was to subtract the Reynolds stresses from the momentum equations via source terms and then add the scaled Reynolds stresses again. This approach is very unstable and it is very difficult to get converged results.

Does anyone know a better/easier way to scale the Reynolds stresses calculated from FLUENT?

Thanks Markus
