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