Hi there,
I'm trying to make use of the great software that is Cfmesh in order to mesh an axial fan. However, I am getting an issue where the blade is not being meshed properly, and I'm unsure what's causing it or how to fix it. The best way to describe is through a picture, and so one is attached here. The .stl of the blade is shown along with it's mesh. As can be seen, the mesh size is small enough to describe the geometry of the blade. Below is also my meshDict, if it helps.

EDIT:
Sorted it out. It was the use of keepCellsIntersectingPatches was what was causing issues

surfaceFile "merged.stl";

maxCellSize 0.05;

boundaryCellSize 0.005;

minCellSize 0.0005;

keepCellsIntersectingBoundary 1;


localRefinement
{
    "blade.*"
    {
        cellSize 0.0006;
    } 
}

boundaryLayers
{

    patchBoundaryLayers
    {
        "blade.*"
        {
            nLayers           8;

            thicknessRatio    1.2;

            maxFirstLayerThickness 0.0015;

            allowDiscontinuity 1;
        }
    }
}

renameBoundary
{
    defaultName        fixedWalls;
    defaultType        wall;

    newPatchNames
    {
        "blade.*"
        {
            newName    blade;
        newType     wall;
        }
 
        "inlet.*"
        {
            newName     inlet;
            newType     patch;
        }

        "outlet.*"
        {
            newName     outlet;
            newType     patch;
        }

        "symm.*"
        {
            newName     symm;
            newType     symmetry;
        }

        "right.*"
        {
            newName     right;
            newType     symmetry;
        }

        "left.*"
        {
            newName     left;
            newType     symmetry;
        }
    }
}

keepCellsIntersectingPatches
{
    "blade.*"
    {
    keepCells 1;
    }

    "symm.*"
    {
    keepCells 1;
    }
}

forgot to upload the image! sorry

Does the issue remains when you use smaller cell near the edge?

I made use of keepCellsIntersectingPatches on the region above (the shroud) where this error occurred.
