about "Angular Deviation"

misu · November 11, 2009, 02:11

dear all:
after generate 3D, the mesh quality report shows that Angular Deviation of some cells is larger than 40°, but i'm a green bird... could u tell me how to adjust the cell?
thank u for ur help^^

This usually happens if your blade is twisted in spanwise direction. You might try to increase the Span Interpolation from up to 5% (middle left in the GUI: Mesh Control -> 3D mesh control).
Much more important concerning quality are skewness (>15°) and expansion ratio (<2.8).

change the intersection quality from low to high in intersection control. the angular deviation will decrease
