I started the simulation in ANSYS 17.1 Static structural. I took three joints and applied joint loads with a 6 degree increment in a second (which is the velocity at which it operates) and defined 360 deg rotation for 60 seconds. For some reason the antenna dish and the ribs on either side of the dish start expanding while rotating. I cannot figure out why. Please help me find the reason for this or let me know if there&#8217;s anything that is wrong with the inputs given.&nbsp;<\/p>\n<p><\/p>\n<p>Regards,&nbsp;<\/p>\n<p><\/p>\n<p>Madhumita<\/p>\n","protected":false},"template":"","class_list":["post-33541","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["5713"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["1222"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["33541"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","157493","162753"],"_bbp_voice_count":["3"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["79647"],"_bbp_last_active_id":["79647"],"_bbp_last_active_time":["2019-03-06 17:17:19"]},"test":"madhumitac93"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/33541","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\/33541\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=33541"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
