Hi Everyone,
I am using MRFSimpleFoam for my fan simulation, I had some non-orthogonal cell so I have given limited 0.5 for laplacian scheme. My simulation is running without bounding error, but the convergence plot looks strange. epsilon is fluctuating too much (see the fig). can you guys give me some tips to fix this fluctuation. wall functions are: k --> kqRWallfunction e --> epsilonWalfunction nut --> nutWallFunction solvers: p --> GAMG epsilon --> smoothSolver smoother GaussSeidel give me some suggestions, where I am doing wrong. Thanks, Sivakumar |
