Hello, I am preparing a simulation of an irregular water channel. The geometry is quite simple, with a k-epsilon turbulence model, however even by changing the parameters/mesh size I cannot reach the convergence, by checking the different plots.
Here below is a draft solution (not converged) of the velocity field
and here the convergence graphs:
Any advice on how to improve the results ( sim parameters, mesh refining etc) it would be hugely appreciated. thanks!
