geometry
{
    target.stl
    {
        type        triSurfaceMesh;
        name        target;
    }    
    
};

对椭球体区域进行加密

    refinementRegions
    {
            target
            {
                mode inside;
                levels ((1E15 5));               
            }    
    }

    locationInMesh ( 39 39 59 ) ;

我设置了不同的levels ((1E15 0)); levels ((1E15 3)); levels ((1E15 5));
之后使用toposet分别定义物体和地面

    {
        name    target;
        type    cellSet;
        action  new;
        source  surfaceToCell;
        sourceInfo
        {
            file            "constant/triSurface/target.stl";
            outsidePoints   ((39 39 59));    
            includeCut      false;          
            includeInside   true;          
            includeOutside  false;           
            nearDistance    -1;              
            curvature       -100;       
        }
    }    

    {
        name    target;
        type    cellZoneSet;
        action  new;
        source  setToCellZone;
        set     target;           // cellSet
    }

    {
        name    floor;
        type    cellSet;
        action  new;
        source  boxToCell;
        box     (0  0 -2)(41 41 0);
    }

    {
        name    floor;
        type    cellZoneSet;
        action  new;
        source  setToCellZone;
        set     floor;
    }


随着level增加，网格越接近椭球体，但地面越来越不平整，该如何解决？

希望能得到帮助
