How to sample a cut in domain which respects boundary conditions
 
Hi everyone,

After running a laminar, axisymmetric, case in OF2.1.0 I run into the following problem:

I am extracting pressure and velocity in a slice through an axisymmetric domain sampling a steady solution after it finished and not getting what I expected.

Mainly, this procedure either doesn't extract the field values at each boundary, for example Ux=Uy=Uz=0 at Wall, or it just extrapolates some value at the boundary without paying attention to the type of boundary it is.

If I transform the solution to FLUENT, and extract from there the same slice, I get the field values I should expect at boundaries.

I would like to avoid going through FLUENT every time.

Thanks!
