Hi all,

I have a geometry with more than one periodic pair. when I expoert the mesh to Fluent I found each pair has different rotational angle ( some negative others positive with same magnitude)..Any idea..

Cheers

well, could you please explain a little bit more. With a diagram in a doc file and pls send it to me.

I worked with periodic BC for long time. I have never had this kind of problem.

In PBC we consider, the flow will repeat after certain angle we set. The faces are to be of same where the repeatational takes place.

Now whats yor prob please ? You have two pair of PBC? and you can't make it work?

The case is simply a multi passages swirler. The passages are inclined 45 degrees to swril the flow. 45 degrees segment will be enough to slove rather than full swirler. I had 4 faces to be considered as PBC on both sides of the 45 deg sector. I hope it is clear now. Thanx Jim
