Class
    Foam::extrudePatchMesh
 
Description
    Mesh at a patch created on the fly. The following entry should be used
    on the field boundary dictionary:
 
    Example:
    \verbatim
        // New Shell mesh data
 
        extrudeModel    linearNormal;
        linearNormalCoeffs
        {
            thickness       40e-6;
        }
        nLayers         50;
        expansionRatio  1;
        columnCells      true;
 
        // Optional feature angle to avoid extruding feature-angles
        featureAngle    45;
 
        // Patch information
        bottomCoeffs
        {
            name        "bottom";
            type        mappedWall;
            sampleMode  nearestPatchFace;
            samplePatch fixedWalls;
            offsetMode  uniform;
            offset      (0 0 0);
        }
 
        topCoeffs
        {
            name        "top";
            type        patch;
        }
 
        sideCoeffs
        {
            name        "side";
            type        empty;
