I am still working on improving my 3d-printer part cooler design.I have resolved most of the issues with my simulation, but I noticed in my latest free-air test case that the airflow seems to be doing something very odd, as the simulation time is extended. The airflow seems to start accelerating, and is wandering off into a directional stream in unexpected directions. I am thinking there is something I don’t understand about pressure outlets.
