Hi all,

Anyone tried to use multigrid in 1.6 version of OF.

I wan't to set
1. V cycle type for Pressure (for pressure termination value being 0.0001), alpha,
2. Flexible cycle type for Ua, Ub k and epsilon (Termination and restriction value being 0.01 and 0.07 respectively).
3. smoother type ILU

these are the changes what I made in Fluent and I wan't to incorporate the same changes in OF also

any one suggest me what changes I have to make in my fvSolution file

I included the following in fvSolution
tolerance 1e-8;
relTol 0;

smoother DIC; //GaussSeidel;
nPreSweeps 0;
nPostSweeps 3;
nFinestSweeps 2;

cacheAgglomeration true;
nCellsInCoarsestLevel 20;
agglomerator faceAreaPair;
mergeLevels 1;

but how do I include termination and restriction values.
