calculate height of first cell
 

Hi Guy's
there are lots of discussions in the forum that the yPlusRAS post processing tool from OpenFOAM doesn't calculate the real yPlus, which is not really a problem. It is easy to calculate the yPlus by using some well known equations in Paraview.
My problem is, that I'm using an unstructured mesh with different first cell heights. I could calculate yPlus for different first cell heights and I know for which area the yPlus in my mesh would be correct but is there any easier way to get the first cell height in a cell data?
