Hello everyone,
I tried pUcoupledFoam for simulation of laminar flow over a square cylinder for several days, but I can't obtain a converged solution. While simpleFoam works for the same case. Would someone please give me some instructions? I used foam-extend 4.1 in my test. My settings for the solver is like this: solvers { Up { solver AMG; cycle V-cycle; coarseningType AAMG; norm componentNorm; normComponent 0; nPreSweeps 4; nPostSweeps 4; groupSize 2; minCoarseEqns 4; nMaxLevels 10; scale on; smoother ILU; minIter 1; maxIter 500; tolerance 1e-9; relTol 0.0; } } Thank you.

might be useful to report the problem to foam-extend. see the issue-reporting link below for the foam-extend issue tracker.
