Additionally in the documentation I find the term CFL-Number (e.g. Fluent 2021R1 Theory Guide 28.4.4.2 Under-Relaxation of Equations). Do these terms mean the same thing? I know that they are closely related, but are there small but decisive differences or do they mean exactly the same?<\/p>\n","protected":false},"template":"","class_list":["post-247618","topic","type-topic","status-closed","hentry","topic-tag-courant-number","topic-tag-fluent"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["245942","15180","22555"],"_bbp_author_ip":["23.56.168.190"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1823"],"_bbp_status":["publish"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["247618"],"_bbp_forum_id":["27792"],"_bbp_engagement":["15180","22555","245942"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["248706"],"_bbp_last_active_id":["248706"],"_bbp_last_active_time":["2023-02-06 10:53:15"]},"test":"oll5hbdfkmozmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/247618","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\/247618\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=247618"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
