How to solve this problem? (68.8 MB)

It looks like you are running with SMP. Does the same problem occur when you run in serial mode?

This problem still occurs when I use dmp

Your mesh not well resolved and not watertight. The Boundary conditions are also not well defined. You have a pressure outlet defined away from the closed stl geometry and the MFiX box is much larger than the tube.
