What would be an appropriate value for the global Courant number when using adaptive time stepping?&lt;\/p&gt;&lt;p&gt;For explicit methods, it is common to select a value around 1 based on the CFL condition. However, how can the Courant number be estimated for the implicit method?&lt;\/p&gt;&lt;p&gt;Thank you very much for your answers!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-398626","topic","type-topic","status-publish","hentry","topic-tag-autotimestepping-1","topic-tag-ImplicitVOF-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["398626"],"_bbp_subscription":["341799","199"],"_bbp_author_ip":["147.86.223.241"],"_bbp_last_reply_id":["403297"],"_bbp_last_active_id":["403297"],"_bbp_last_active_time":["2025-01-02 14:18:24"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["341799","199"],"_btv_view_count":["801"],"_bbp_topic_status":["unanswered"]},"test":"claudedavid-spirgifhnw-ch"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398626","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\/398626\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=398626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
