How to block this geometry?
 

Hey guys,
I really need help blocking this inlet.
The fluid (air) enters the part from the back.
I'm not sure how to block this geometry to get a proper result.
It would be nice if you could tell me how to cut the blocks.

Thanks in advance!

two blocks could be sufficient in my humble opinion.

Thanks for you answer.
I still have another problem with that kind of blocking:
the face between the orange and the yellow line always gets associated to the following geometry/blocks with follow this part of geometry.
I dont seem to be able to handle that.

you can disassociate that face if you wanted to do so by going to - Blocking --> Edit associations --> Disassociate from geometry and then select the faces to disassociate
