An overflow was encountered&#8221;. Please also check the weird drag force resultant of one of the monitored silos Fx Col2M (that is the one in the middle of the arrangement). <\/p>\n<p> This simulation was meant to evaluate the drag coefficients of a silos in a silo-arrangement with an aerodynamic CFD simulation. This is a quasi-2d simulation. <\/p>\n<p> Against all my efforts I did not manage to get a steady solution, I guess too many cylindrical shapes are involved, so instabilities are controlling the convergency. That&#8217;s why I tried to run a 30-sec transient simulation. <\/p>\n<p> 1.) Please help me to fix the issues in the&nbsp; <\/p>\n<p> 2.) In the meantime If can, by knowing my model, please give some &#8216;specific&#8217; (not general) hints how to try to achieve an acceptable convergency with steady state. <\/p>\n<p> Please find the Wetransfer link of the project archive (without results):&nbsp; <\/p>\n<p> Thanks <\/p>\n","protected":false},"template":"","class_list":["post-254162","topic","type-topic","status-closed","hentry","topic-tag-aim-faq","topic-tag-discovery-aim-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["30411"],"_bbp_likes_count":["0"],"_btv_view_count":["317"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["254162"],"_bbp_forum_id":["27789"],"_bbp_engagement":["3452","30411"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["259326"],"_bbp_last_active_id":["259326"],"_bbp_last_active_time":["2022-01-06 09:03:06"]},"test":"infosteelxpert-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/254162","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\/254162\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=254162"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
