Boundary conditions are far-field and symmetry and the domain is a sphere. But even \u0131 tried with the smaller mesh numbers (4 million- 2 million these are the mesh elements that I tried ) I couldn&#8217;t get the solutions, it took so long. I tried with SST- k omega and Spalarat Allmaras, Implicit solver green gaus node based, and other things are defaulted. What is your suggestion for this type of problem to get a better solution? Please help me because I think I am gonna lose my mind if I take another error from ANSYS.&nbsp;<\/p>\n<p>Thank you.<\/p>\n","protected":false},"template":"","class_list":["post-304694","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["20574","8124"],"_bbp_author_ip":["96.7.74.173"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["377"],"_edit_lock":["1693748113:229770"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["304694"],"_bbp_forum_id":["27792"],"_bbp_engagement":["8124","20574"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["304937"],"_bbp_last_active_id":["304937"],"_bbp_last_active_time":["2023-09-05 10:59:21"]},"test":"selinerooglu92gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/304694","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\/304694\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=304694"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
