Class
    Foam::patchDistMethods::exact
 
Description
    Calculation of exact distance to nearest patch for all cells and
    boundary by constructing a search tree for all patch faces.
 
Usage
 
    \begin{verbatim}
    wallDist
    {
        method          exactDistance;
 
        // Optional entries (currently for distributedTriSurfaceMesh)
        exactDistanceCoeffs
        {
            // Optional decomposition method. If not supplied will use the
            // system/decomposeParDict.
            method              hierarchical;
            numberOfSubdomains  8;
            n                   (2 2 2);
 
            // (not)add fill-in triangles
            decomposeUsingBbs   false;
        }
    }
    \end{verbatim}
