I used hex dominated mesh method and the size of mesh is 0.005m. The inner vortex does not form and I do not have escape particles. 261151 particles are injected and 160 particles are trapped, does anyone know what is the problem? And is the problem related to the damping factor? Is it similar to the relaxation factor in the &#8220;solution method&#8221; section?<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/09\/27-09-2023-1695851090-Screenshot (627).png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-309186","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["292886","199"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["478"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["309186"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","292886"],"_bbp_voice_count":["2"],"_bbp_reply_count":["9"],"_bbp_last_reply_id":["312257"],"_bbp_last_active_id":["312257"],"_bbp_last_active_time":["2023-10-19 09:27:27"]},"test":"mahsatorkaman-ayahoo-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/309186","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\/309186\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=309186"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
