Specifying Friction Coefficient in OpenFoam
 

Dear Foamers,

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.:)

Hi,

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.
