Currently, we&#039;re in the meshing stage and we&#039;re using Ansys Fluent Meshing. We now have an accurate mesh, but in order to still increase the efficiency, we&#039;re doing a convergence study of the most difficult parts. When we adjust a certain parameter (for example; decreasing the max and min cell size of the surface mesh at a certain place) we get the error &quot;After Surface Mesh, the model consists of 5 free nodes that could not be repaired. The CAD needs to be repaired before proceeding.&quot;<\/p>\n<p>We think it&#039;s weird that we get this error, since we&#039;re using the same CAD file as before. What are these free nodes and why are we getting this when we&#039;re just trying to decrease the cell size? <\/p>\n<p>Sometimes, when we adjust the max cell size, we don&#039;t get this error. Maybe a better understanding in these free nodes will get us a better insight in solving this problem.<\/p>\n","protected":false},"template":"","class_list":["post-166769","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["2001"],"_bbp_likes_count":["0"],"_bbp_subscription":["244818"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["166769"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","244818"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["206758"],"_bbp_last_active_id":["206758"],"_bbp_last_active_time":["2022-02-28 17:06:50"]},"test":"dries-timmermans33gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/166769","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\/166769\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=166769"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
