sampleDict - Problems with distanceSurface
 
Hi,

I try to sample my velocity data with distanceSurface (using OF 201) and getting this error:

Code:

Have anyone an idea what's wrong?

Because when I try to sample the same case with OF17 it runs fine (without any errors), but the results are verry weird!

Here are my sampleDict:

did you ever get a reply?
 
Hi Kris,

I'm trying to use distanceSurface to sample at specific heights above my surface, for flow simulation in the atmospheric boundary layer - exactly what you are doing (according to the name of you stl file).

Did you ever solve your problem?

I have some additional questions , but first thing first, hope you answer.

Hanan.
