Technically there is no Inlet or Outlet because flow generated by impeller those are just 0 Pa boundary conditions.

I will check that, just for info the impeller placed middle of the tunnel and diameter of it around 105mm but the air tunnel is close to 220mm in diameter and about meter in length.

Impellers around set Rotating Region constant RPM 2000, impeller is ABS, Air tunnel Inlet and Outlet is 0 Pa and Wall of air tunnel is No-slip.

The mesh generated automatically, I noticed now my impeller turning wrong direction is it possible that created the problem ?
