Hi all,

I'm doing a centrifugal compressor simulation. To speed up the simulation, I want to use only a blade passage instead of the whole geometry. To get this, I have to slice the geom to a periodic piece. What is the recommend way?
1. Slice between the blades, so I get a geometry bounded by periodic boundary conditions with a blade in the middle, or
2. Slice at the centroid of the blade, so I get a clear blade passage, bounded by blade walls.

I found examples for the type 1., but the second one seems to be good too.

Thanks for any advice,
Attesz
