CFD Online Discussion Forums - dynamicRefineFvMesh

Hi all,
I am doing a simulation of impinging jets ,which needs high quality mesh.It is necessary for me to use the dynamicRefineFvMesh fuction.But I have no idea about how to set the specific parameter , and what they mean.Thanks a lot

PHP Code:


		
			
dynamicFvMesh   dynamicRefineFvMesh;

dynamicRefineFvMeshCoeffs
{
    // How often to refine
    refineInterval  1;
    // Field to be refinement on
    field           alpha1;
    // Refine field inbetween lower..upper
    lowerRefineLevel 0.001;
    upperRefineLevel 0.999;
    // If value < unrefineLevel unrefine
    unrefineLevel   10;
    // Have slower than 2:1 refinement
    nBufferLayers   1;
    // Refine cells only up to maxRefinement levels
    maxRefinement   2;
    // Stop refinement if maxCells reached
    maxCells        200000;
    // Flux field and corresponding velocity field. Fluxes on changed
    // faces get recalculated by interpolating the velocity.
    correctFluxes
    (
        (
            phi
            U
        )
    );
    // Write the refinement level as a volScalarField
    dumpLevel       true;
