I am working on improving the airflow of a part cooling fan duct for a 3d printer. I am now able to get fairly good results with the simulation. I have two minor issues, however.
First, when I add particle traces to the simulation run, they don’t seem to be retained in the system, so I need to re-add them every time I want to see the view. Is there a way to make this consistently sticky? I am fairly sure they have stayed under some circumstances, but definitely not consistently.
Second, after I first generate the run, it is essentially empty, but when I return to it later, there are cylindrical worm tracks that appear to be some version of the particle traces on one side of the simulation. I have no idea what they are representing, or how to hide them.
The Simulation that was taken from is:
I should note that the worms are now visible in the screenshot, but not in the simulation, so consistency is still a little off…
