Distance between boundary cell and boundary face
 

Hi

I wanted to find out if there is a function in OpenFOAM that directly gives you the distance between boundary cell center and boundary face centre. I wanted to use it for coding my boundary condition.

I know that there is function (\delta()) that exists in swak4foam in groovyBC but I cannot directly use it in OpenFOAM.

Thank you.

Hi,

If you have a look at yPlus.C (in OF 3.0.0):

which should do what you need I think. The description of this class reads:
"Distance calculation for cells with face on a wall. Searches pointNeighbours to find closest."

All the best,
