Why doesn’t the /CYCEXPAND display of modal cyclic symmetry results with the phase angle given by CYCPHASE match the CYCPHASE max values?
March 17, 2023 at 9:00 amFAQParticipant
CYCPHASE uses Full Graphics to determine the maximum value. /CYCEXPAND uses PowerGraphics, which is known to give slightly different values of stress, particularly at stress concentrations. This is due to the use of only elements with faces on the surface by PowerGraphics and its suppression of averaging at material, thickness and geometry discontinuities.
