If this is an industrial sized wind turbine blade, it sounds like perhaps the cut-off trailing edge is resembling a sharp knife-edge.  Some possible workarounds:

-Turn off the "Cut-off or Square"  trailing edge definition in TurboGrid.  Using a different topology for the trailing edge may avoid the error

-Try scaling up the geometry in DesignModeler by a reasonable value such that the mesh generates in TurboGrid.  Scale the mesh back down in CFX-Pre.

-Modify the geometry in DesignModeler to avoid this knife edge (if that's what's causing the issue).  Dimensions that small for such a large geometry aren't realistic
