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.
