outlet = inlet in a periodic geometry

Stephane bone

Hi,

I have to model the flow in a static mixer. A static mixer has no moving parts. It is made of single elements fitted in a pipe. These elements are placed and rotated by 90° one after each other.

Then, every two elements, I have the same model to solve. In order to study a longer static mixer, I would like to mesh a static mixer with two elements and use the outlet of the first two elements as the inlet of the two following elements...

So, my questions are : - Is it possible to export the results of the first run in an output file and introduce it as the inlet of the next run (with BCDEFI?) - Is it necessary to have exactly the same mesh at the outlet and the inlet?(It is not the case in my model due to the rotation by 90°)

Thanks for your help

Stephane
