Hi All
as you know, there is many options for divSchemes, laplacianSchemes, and so on ...

also there is many linear solver such as: GAMA, smoothsolver and PCG/PBiCG

In OpenFoam forum there is not a good thread to explain that how we can select a good scheme and solver for different problemes

please share your information about different options of fvScheme and fvSolution and compare them and explain which is the best for a specific problem

Best Regards

Hi Elvis
yes, it is a good document
But I want to collect the suitable scheme for each different problem

for example when we should use GAMG, smoothSolver or BiCG solvers ?
or in divSchemes when we should use the bellow schemes for div(phi,U) ?

div(phi,U) Gauss upwind;
div(phi,U) Gauss limitedLinearV 1;
div(phi,U) Gauss linearUpwind grad(U);
and in similar way for gradSchemes and laplacianSchemes


Best Regards
