Hello Max,

Thank you for looking into my bug report.
Your comment regarding how the population is stored into the cell values was very helpful. And indeed, with that in mind, my bug report was erroneous.

Since I am relatively new to the LBM scene, I was not aware that such measures are taken to reduce the numerical roundoff error. Perhaps it would be nice to make that clear in the documentation. Technically, it is written in there on page 49 (olb_ug-1.3r0), but only in one sentence, which can be easily read over.

Thank you for your time and help!

Regards, Julius
