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 a number of correction iterations.
Example of the wallDist specification in fvSchemes:
wallDist { method meshWave; // Number of corrections nCorrectors 3; // Optional entry enabling the calculation // of the normal-to-wall field nRequired false; }
