Hello everyone,

in order to calculate y+ in my quasi-3D simulation of the ReD = 3900 cylinder flow benchmark, I tried the surfdistance module within FieldConvert fo calculate the height of the near-wall prism layer elements. Since surfdistance threw an error indicating that quasi-3D models are not supported, I first used the meanmode module to get a spanwise averaged planar field and then tried it again with that. However, the surface distance is equal to zero over the whole cylinder wall.
In the next step I extruded my 2D mesh to 3D with NekMesh extrude utility, but receive the same results: the calculated surface distance is 0 everywhere (see attached pic) with no errors during the calculation.

Am I missing something? What would be the correct way to use surfdistance?

Thanks and all the best
