@JqBu 找到个of官方算例动态加密网格的，是下面这样，不过在我的算例里还是跑不了，贴出来记录一下把

topoChanger
{
    type            refiner;

    libs            ("libfvMeshTopoChangers.so");

    // How often to refine
    refineInterval  1;

    // Field to be refinement on
    field           alpha.water;

    // Refine field in between lower..upper
    lowerRefineLevel 0.001;
    upperRefineLevel 0.999;

    // 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. Use 'none'
    // on surfaceScalarFields that do not need to be reinterpolated.
