Laplacian term missing in simpleFoam - UEqn.H
I am trying to understand the code for simpleFoam and I came across the wiki for the same
the second equation says that the
fvm::div(phi, U) - laplacian(nu,U)
But in the actual file UEqn.H in the /solvers folder , the code is as below
Is the laplacian term replaced with a turbulence term??
Can someone help to figure this out?
Your help is highly appreciated.
Hi, simpleFoam manages both laminar and turbulent cases via turbulence->divDevReff(U). This term reduces to the laplacian one in laminar cases.
Thanks a lot for your reply:)
