Distance function
 

Dear OpenFoam users,

I have a simple (but a bit confusing me :)) purpose to study different approaches for wall distance computations, typically used in turbulence computations, but I have no idea where in Openfoam I have to start to compute or plot it.

Can it be computed without running RANS or LES model?

As far as I know there are three options to compute the wall distance in OpenFoam: using meshWave, Poisson or Eikonal euqation. The later one is of my interest.

Could anyone guide me with this please?

Thanks,
Dmitry

Yes, it is called DNS. :D

Well, sure, but seriously speaking I need to test the wall distance without running any NS solver.
