      For radial pumps, occasionally TurboGrid is not able to properly locate the leading edge. It needs to define this location for the mesh templates to be aligned properly with the geometry. When this occurs, poor mesh quality or negative volumes result. The Blade Set CCL in TurboGrid can be modified to remedy this. To do this, right click on Blade Set and select Edit in Command Editor. The line of CCL to be modified is: Blade Edge Detection Space = Auto For all blades, it should be changed to: Blade Edge Detection Space = Cartesian Click Process.
