I cut my model so that it represents an eighth of my actual geometry and used cyclic symmetry to get the results on the full model. Unfortunately, I get high stresses along the edge of the face I used as low\/high boundary. <\/p>\n

It is important to note that this edge is part of a contact region and that I do expect high stresses in that region. I tried modelling a quarter model and the high stresses went away for the region that I didn’t cut (i.e. every other edge from the original eighth). Ideally, I would just model the full geometry, but unfortunately that would take very long to solve and I would like to avoid that. <\/p>\n

Is it not valid to define cyclic symmetry in contact regions\/regions of higher stresses then?<\/p>\n

And can I safely assume that the stresses in my quarter model are correct (in the region where I didn’t cut compared to the eighth model)?<\/p>\n","protected":false},"template":"","class_list":["post-365175","topic","type-topic","status-closed","hentry","topic-tag-cyclic-symmetry","topic-tag-symmetric-boundary-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
