Dear Sirs
In my model there are some sharp feature > 90 degree Feature Angle
After change Options>Mesh>Feature Angle to 150 (or 180 maximum) degree, I could not select elements 'by face'
Whether hypermesh performed incorrect calculation for it?
right photo indicate normals of elements are correct in such way they form a >90 degree-angle
