Due to the complexity of the geometry of my tyre, main concern with my model is the number of elements and nodes. I have tried using either the shared topology method (in SpaceClaim) or the connection method (in ANSYS mechanical). I like the idea of the Shared topology method as the mesh on the contact surfaces match, however, my issues arise when I try applying a meshing method or size to my model. <\/p>\n<p>I followed a similar method as used in the video <a href=\"https:\/\/www.youtube.com\/watch?v=itbYd0LLDyk\" rel=\"nofollow\">https:\/\/www.youtube.com\/watch?v=itbYd0LLDyk<\/a>, however, applying mesh sizing and methods to the model gives me errors.<\/p>\n<p>Firstly the geometry (even after meshing) has the &ldquo;?&rdquo; symbol next to it. I have shared the topology between all flexible bodies but did not include the rim (as it is a rigid body) in that step.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/VYO38QDS2DY6\/tree.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/VYO38QDS2DY6\/tree.png\" alt=\"tree.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-47058","topic","type-topic","status-closed","hentry","topic-tag-mesh-generation","topic-tag-mesh-sizing","topic-tag-shared-topology","topic-tag-species-transport-model","topic-tag-structure"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["19253"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["?\u0006sM"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["6013"],"_bbp_subscription":["254179"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["47058"],"_bbp_forum_id":["27789"],"_bbp_engagement":["62","200","180068"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["123624"],"_bbp_last_active_id":["123624"],"_bbp_last_active_time":["2020-08-06 11:53:43"]},"test":"kirstenbraun"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/47058","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\/47058\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=47058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
