ancolli is on a distinguished road
I am learning how to use groovybc in laplacianFoam in steady state.

bcwall1
{
type groovyBC;
value uniform 10;
valueExpression "1+0.5*T";
}

in laplacianFoam, if I set nNonOrthogonalCorrectors = 1 inside fvSolution the valueExpresion will be 6 (after 1 iterarion). if I set nNonOrthogonalCorrectors = n this value will tend to 2 as n increases.

while (simple.correctNonOrthogonal())
{
solve
(
fvm::ddt(T) - fvm::laplacian(DT, T)
);
}

my doubt is how to control the convergence over the bc whitout trial and error of n.
