The tutorial articles show examples of doing small 3D simulations that account for objects that possess inversion symmetry about specific axes, but I am interest in simulating objects that are unchanged by ANY rotation about the y axis. <\/p>\n<p><\/p>\n<\/p>\n<p>Thanks,<\/p>\n<p>Adam<\/p>\n","protected":false},"template":"","class_list":["post-162517","topic","type-topic","status-closed","hentry","topic-tag-LumericalFDTD-1","topic-tag-rotationalsymmetry-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2839"],"_bbp_likes_count":["0"],"_bbp_subscription":["233331"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162517"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","187429","250776"],"_bbp_voice_count":["3"],"_bbp_reply_count":["15"],"_bbp_last_reply_id":["192993"],"_bbp_last_active_id":["192993"],"_bbp_last_active_time":["2022-03-28 17:07:51"]},"test":"abacker"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162517","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162517\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162517"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
