Detailed Description

Fast topological mesh-wave method for calculating the distance to nearest patch for all cells and boundary.

For regular/un-distorted meshes this method is accurate but for skewed, non-orthogonal meshes it is approximate with the error increasing with the degree of mesh distortion. The distance from the near-wall cells to the boundary may optionally be corrected for mesh distortion by setting correctWalls = true.

Example of the wallDist specification in fvSchemes:

    wallDist
    {
        method meshWave;

        // Optional entry enabling the calculation
        // of the normal-to-wall field
        nRequired false;
    }
