Hi,
Running fine fractions with PIC often yields this “still not cool” message, which I understand means that parcels/particles are removed from the system. This is also visible in the inventory plot below. I have so far tried to reduce the timestep and statistical weight, without any luck. The message still appears when trying with uniform and larger particle sizes (within the original PSD).
There is one post on the same topic here on the forum, but I couldn’t find what else to try, as I interpret “fluid timestep” as the main timestep found in the “Run” section. Any other advice?
This inventory curve is based on a stepped inlet velocity increase, thereby the accelerated removal of particles.
