Hello folks,

I am trying to snap an object on top of the airfoil shape. The mesh was not created using blockMesh, instead I used the following codes to create my meshes:
Code:
plot3dToFoam -2D 0.1 -noBlank -noFunctionObjects n0012_113-33.p2dfmt
autoPatch 30 -overwrite
createPatch -overwrite
extrudeMesh
Then I try to snap my object on the airfoil shape, I keep failing in doing so. The error is as follows:
Code:
slurmstepd: error: Step 2361478.4294967294 hit memory limit at least once during execution. This may or may not result in some failure.
SHM file:
Code:
castellatedMesh true;
snap            true;
addLayers       false;

geometry
{
    VorGen.stl
    {
        type triSurfaceMesh;
        name VorGen;
	tolerance 2;
    }
};


castellatedMeshControls
{
    maxLocalCells 300000;

    maxGlobalCells 50000000;

    minRefinementCells 0;

    maxLoadUnbalance 0.10;

    nCellsBetweenLevels 3;

    features
    (
	{
		file "VorGen.eMesh";
		level 5;
	}
    );

    refinementSurfaces
    {
        VorGen
        {
            level (5 5);
            patchInfo
            {
                type wall;
            }
        }
    }

    resolveFeatureAngle 30;

    refinementRegions
    {
    }

    locationInMesh (0.095 0.05 -0.05);

    allowFreeStandingZoneFaces true;
}

snapControls
{

    nSmoothPatch 3;

    tolerance 2.0;

    nSolveIter 300;

    nRelaxIter 5;

        nFeatureSnapIter 10;

        implicitFeatureSnap true;

        explicitFeatureSnap false;

        multiRegionFeatureSnap false;
}
