Hello to all,

I have a problem on simulating a coal gasifier with four tangential inlets.
I've splitted the domain considering a quarter, and applying the rotational periodic boundary.

The jet flow penetrates through the periodic boundary. When I reconstruct the entire domain, it is possible to observe a discontinuity on the jet flow when it cross the periodic boundary.

Do you have some advices to solve this problem?

Thank you for your attention,

best regards

Michele
