Hello,

I am trying to put in the Van Driest damping function for a turbulence model.

One of the statements that go in it, is:

volScalarField Re_t = sqrt(k_)*(y_/nu());

This generates an error. That is because of the usage of 'y_', which is basically the position of the cell center in the mesh.

Is there an inbuilt function to access the y position of the cell centers as a volScalarField for this pupose? Can anyone recommend an alternative strategy to implement the above?

Thanks!

I found some information on this post:

#include "wallDist.H"
...
...
volScalarField y = wallDist(mesh_).y();

This seems to do get the wall distance!
