I am glad to hear that you made progress with your showcase.
To assess the velocity field, you can use SuperLatticeVelocity3D, transform that via AnalyticalFfromSuperF3D and then use the resulting function with the typical (output, input) structure.
With the input value you can specify the location of the probe.
Please note that this procedure can be found in various examples.
Considering the parallel mode, we can recommend MPI.
Since I have not encountered the OMP issue before, I can not help you with that right away.
