I am trying to couple the Transient structural module with the Fluent via a Coupling system. However, I received either a &#8220;highly distorted element&#8221; error or &#8220;negative cell volume detected&#8221; in almost all the cases. To resolve the issues, I have tried:<\/span><\/p>\n<p><span style=\"font-size: 12pt\">1- refining the mesh in both structural and fluent modules;<\/span><br \/><span style=\"font-size: 12pt\">2- reducing the system coupling time step.<\/span><\/p>\n<p><span style=\"font-size: 12pt\">I could not yet, however, get a converged solution. Can anyone please tell me any suggestions or advice?<\/span><\/p>\n<p><span style=\"font-size: 12pt\">I can provide more detail if necessary.<\/span><\/p>\n<p><span style=\"font-size: 12pt\">Thanks!<\/span><\/p>\n","protected":false},"template":"","class_list":["post-240118","topic","type-topic","status-closed","hentry","topic-tag-fsi"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["79313","805","273197"],"_bbp_author_ip":["23.56.168.214"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["6149"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["240118"],"_bbp_forum_id":["27792"],"_bbp_engagement":["805","79313","273197"],"_bbp_voice_count":["3"],"_bbp_reply_count":["24"],"_bbp_last_reply_id":["301228"],"_bbp_last_active_id":["301228"],"_bbp_last_active_time":["2023-08-13 16:58:21"]},"test":"s-m-mousavipm-univpm-it"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/240118","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\/240118\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=240118"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
