Could I be right or wrong when I understand the manual section 7.43 “*DLOAD” in such manner that the axis of rotation can be any axis defined by 2 different coordinates, or should centrifugal loading always be around one of the main axis, because when I run the listed dataset where the axis of rotation is defined by (0,-5,0),(0,-5,1) I get the left picture which is obviously wrong alternative with all y-coordinates raised by 5 and axis of rotation defined by (0,0,0),(0,0,1) I get the right result shown in the right picture.
** Pie Cut Symmetry brick under centrifugal loading
** Unchanged Dataset will generate left picture,
** but with all y-coordinates raise by 5 it will generate right picture
