how to decrease Uy residuals?
1 Attachment(s)
in Residuals I attached Uy are about 10 order bigger than others.
how can I reduce it?
my problem is unsteady and compressible in a long tube with 7cm length and 4mm height.
any help and advice?

Is there a symmetryPlane boundary in your case?

Best regards,

hi dear Fumiya
No.there isn't any symmetryplane in my case.
Its a simple 2D tube with two walls at top and bottom and one inflow and one outflow at sides.
