Calculation of approximate distance to nearest patch for all cells and boundary by solving a Poisson equation.
The scheme is specified using:
wallDist { method Poisson; }
This requires the additional entry in the divSchemes sub-dictionary in the fvSchemes file, e.g.:
laplacianSchemes { laplacian(yPsi) <laplacian scheme>; }
An solver entry for the yPsi
variable is also required for the fvSolution file, e.g.
yPsi { solver <solver>; ... tolerance 1e-5; relTol 0; }
