Dear everyone,

I'm working with a centrifugal compressor, the impeller and radial diffuser grid are generated by Autogrid5(only one channel), the volute grid is generated by GridPro，I want to merge these grids with IGG, could someone tell me how to set the boundary conditions of radial diffuser outlet block patch and the inlet block patch of the volute?

thank you very much
