Discontinuity in results
 

I have set up a model of a wind turbine but seem to be getting a disconnection or discontinuity in my results at the interface between domains. I have set up a mesh connection between the two domain bodies but for some reason it has not given correct results. The mesh size for both bodies is the same in the model.

The results images and the workbench file can be seen/downloaded here:

Any help would be much appreciated.
Thanks
John
