Hello all,

I am trying to set periodic conditions on a SU2 4.0.0 case.

My periodic marker:

MARKER_PERIODIC= ( periodic2, periodic1, 0.0, 0.0, 0.0, 0.0, 90.0, 0.0, 0.0, 0.0, 0.0 )

(I inverted periodic2 and periodic1 to see, but no change)

- I tried to launch SU2_MSH and to use the output mesh.
- I tried to use radians instead of degrees...
- I am sure the center of the periodic rotation is at (0,0,0) and that the angle is 90 degrees from periodic1 to periodic2 around the y axis.
- I have looked through the documentation and found nothing to help.
- The discussions of this forum are about older versions of SU2 and didn't help either.

I have tried lots of things, but nothing works. The flow diverges always as in the enclosed screenshot.

Replacing periodic boundaries by walls make it converge (so, the problem comes from periodical conditions).

Any help would be very much appreciated!...

Best regards,

William
