I am considering convection with bulk fluid temperature at the joint internal and convection with room temperature at the external surface. I read online that time step of transient thermal analysis is determined by using Biot and Fourier Numbers as shown in the attached picture.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/046\/A5WKU04N1PI0.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/046\/A5WKU04N1PI0.png\" alt=\"Time.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-162120","topic","type-topic","status-closed","hentry","topic-tag-structural-and-thermal","topic-tag-time-step","topic-tag-timestep-size-1","topic-tag-transient-thermal"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["3164"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["162120"],"_bbp_forum_id":["27791"],"_bbp_engagement":["200","220348"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["191633"],"_bbp_last_active_id":["191633"],"_bbp_last_active_time":["2021-09-13 12:00:36"]},"test":"mijomo5315ansomesa-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/162120","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\/162120\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=162120"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
