I'm trying to model the situation where there's a fan/heater in an enclosure both heating and circulating air. The problem is the simulation keeps throwing the error "Fan not attached". Fan not attached to what? The fan is attached to the side of the enclosure, and is intended to circulate air within the enclosure, not blow air out of a hole.
If I do attach the fan to a hole in the enclosure then the simulation does not complain, although it's a little confusing as to how the fan would work without an air intake.
As background, I'm trying to determine the best way heat the enclosure to even out temperatures.
