hi,
while I was searching tutorials I found something in some fv solutions Code:
relaxationFactors { fields { p 0.3; } equations { U 0.7; k 0.7; omega 0.7; } Code:
relaxationFactors { p 0.3; U 0.7; k 0.7; epsilon 0.7; R 0.7; nuTilda 0.7; } also some one Code:
relaxationFactors { fields { } equations { "U.*" 1; "k.*" 1; "epsilon.*" 1; } } |

also
in simpleFoam>>pipeCyclic tutorial Code:
PIMPLE { nOuterCorrectors 4; nCorrectors 1; nNonOrthogonalCorrectors 0; pRefCell 0; pRefValue 0; } SIMPLE { nNonOrthogonalCorrectors 0; residualControl { p 1e-2; U 1e-3; "(k|epsilon)" 1e-3; } } |

Hey alyucel, I am not sure about your first question. I am wondering the same thing and never found a good explanation for the syntax.
But to your second post: fvSolution contains info for the solver. The solver "simple" will use all information after the keyword "SIMPLE { ... }". It will just not consider the stuff after "PIMPLE { ...}". So if you have both in one file, you will be able to start your case with both solvers pimple and simple.
