Hey guys,

I'm working on a simulation for a radial compressor. So far it has worked without any problems for different parameters.

Now I have been given the task to give my fluid a certain twist/ swirl which is created in the test bench by a inlet vane control.

For example, I can set the adjusting blades to +10.
Unfortunately, I don't know how to find the right angle here.

I would be very grateful if you could help me!

Many thanks in advance!

Regards,
Arthur
