Hi. I'm new to adaptive mesh refinement (AMR) and using OpenFOAM-3.0 in windows. Everything works fine except that the mesh does not get unrefined when the refinement situation is lifted. My dynamicMeshDict is as follows

dynamicRefineFvMeshCoeffs
{
refineInterval 1;
field Cf;//concentration of a reactive species
lowerRefineLevel 10;
upperRefineLevel 100;// Cf varies between 0 and 165
unrefineLevel 2;
nBufferLayers 0;
maxRefinement 1;
maxCells 40000;
correctFluxes
(
(phi none)
);
dumpLevel true;
}

after a while in simulation, Cf reaches 165 (nearly homogeneous in the whole domain), but the mesh does not get unrefined

Found out that unrefinement happens when the value is lower than unrefine level not higher
