Default Losses in a channel

I am studying losses in a flow domain with several vanes. I use static entropy contours to find the location of high entropy generation. My results show that there is high entropy generation which is concentrated near to a solid boundary. Is there a way to distinguish between the type of losses such as boundary layers, flow separation, mixing loss, tip leakage, secondary (endwall) loss?

Wouldn't it be better to locate such regions with an Isosurface, rather than contours [in a plane]?
To the question on determining the type of loss, I don't think you will get much help from CFX itself on this. Though, a combination of experience and physics understanding, and probe points/surfaces, will make you able to measure the change in quantities. For a channel flow, monitoring Pressure would seem like an obvious place to start.
