Specifying Friction Coefficient in OpenFoam
I am working on dambreak flow in an open channel. can any one help me how to specify manning's roughness coefficient in OpenFoam.
I checked manual and code, no success.
Is there anyway to specify bottom friction in OpenFoam ?
Thank You in advance.:)
There is a rough wall function that I believe can be specified in the nut file. I haven't tried it and I am not sure how to relate the roughness to Manning's, but I think with some searching and research you could come up with something that would work.
