hey i am trying to simulate turbulent open channel flow. but every time it shows an error " Failed to find a solution.
Maximum number of segregated iterations reached.
Returned solution is not converged."
i tried refining the mesh so many times but same error comes again and again.
the dimensions are 50m X 2m X .5m
inlet velocity is 5 m/s
outlet boundary condition is " pressure = 0 "
top surface is taken to be free surface with boundary condition as " open boundary, having no viscous stress "
note: no volume force is used
please help me out if any one has solved this kind of model
Regards
