pitch angles between fluid/solid
 

Hello all.

I have a question regarding pitch angles. I would like to connect 1/11 of the air domain(rotating) with 1/4 of solid domain (static).

But to define pitch ratio I need to use frozen rotor interface. But as soon as I set this option up the error message appears.

Is there any way how to define this interface?

Any idea will help.

Thanks in advance
