Air flow through a cylinder with UDF issues

I see 2 issues:

  1. There is a conflict with your geometry, where the wall cylinder is closed at the y=ymin and y=ymax planes. try to extend the height of the cylinder (say a height of 0.06m instead of 0.05m). You will also get a cleaner cylinder if you use the procedural geometry instead of the implicit shape.

  2. Instead of the Mass outflow BC, use a Pressure Outflow BC.
