Using the localBlended scheme for DES
Good afternoon foamers,
I have a question on the use of the localBlended scheme. The goal is to use a different scheme for the RANS zone and LES zone. I calculate UBlendingFactor in my turbulence model and it returns a surfaceScalarField as it is needed by the localBlended scheme such as UBlendingFactor = 1 in the LES region UBlendingFactor = 0 in the RANS region So far this works fine. Now, my question is pretty simple: How does UBlendingFactor acts when calling the scheme? If I write, in the fvScheme file of my case, something like: div(phi,U) Gauss localBlended upwind linear; Where is it going to be upwind and where is it going to be linear? Thank you for any help, Philippe |
Hi again,
after looking at localBlended.H : blendingFactor*tScheme1_().interpolate(vf) + (scalar(1) - blendingFactor)*tScheme2_().interpolate(vf); It seems that tScheme1 will be effective where blendingFactor=1. So if I want to have a linear scheme for the LES region, I would write : div(phi,U) Gauss localBlended linear upwind; Am I right? |
