Multibody Control Volume - Flow Problem
 

Hello Dear CFD Lovers,
First of all, i am new in forum so please inform me if i am doing something wrong while posting.

Recently i am working on a 3D hex control volumes which has multi bodies. But i formed a new part and they are all in a same zone. Normally there shouldnt be a problem but in Fluent the flow is stacking at the 1st section. All bodies are fluid (air).

It would be nice if you can help me (or inform me if this problem posted-solved before).

Thank you.
Best regards,
Güven

P.s: Yes that is coarsed mesh, i've just wanted to see if the flow can pass through.

I have same problem also. Flow stucks in the body and doesn't go through the body.

I guess that it is not about interfaces. Any reasons for these type of problems ??

Help please, thank you.
