Unusual turning angle ahead of blade leading edge
 
Hey,

I running a couple of 2-D simulations on a High Pressure steam turbine airfoils. The issue I am having is that when setting the flow at 0 incidence angle (i.e along the stagnation line that should result in flow impinging the Leading edge), the flow apparently seems to turn way ahead of the leading edge and the stagnation point lies on the suction side away from the leading edge?

To all the turbomachinery experts, is this spurious? I can provide images of my geometry if needed.

My simulations are all done in CFX version 13

Thanks,
Ryan
