I actually never got this to work, but I'll believe it as the solution. I just made a straight pipe with velocity-inlet and solid injection on the bottom, outflow at the top. Still had problems with meshing, and had one localized area showing air velocity of 4000 m/s when I set a velocity-inlet at 15 m/s. Need to take several steps back and try some more 2D solutions or something.
