Why can't I expand my modal cyclic symmetry solution in a model with SHELL41? When "/CYCEXPAND,,ON", a stress listing has both the real and imaginary results (without the usual warning about unprocessed data). The listing of displacements is correct, and the plotting of stress seems to be correct as well. This also occurs with SHELL181 KEYOPT(1)=1. It does NOT occur with SHELL63 KEYOPT(1)=1 or SHELL181 with KEYOPT(1)=0.

The existence of membrane shells turns out to be one of the many cases where PowerGraphics is turned off without notice, which then turns off /CYCEXPAND. Defect 59982 requests that membrane shells be added to the list of features not supported by PowerGraphics. |
