I want to know the time it takes for the body to attain normal temperature or alternatively for specific time period likle 2s, 3s or 5s, what is the temperature drop in body. I have tried normal steady state approach and Conjugate Heat transdfer approach using stead state and transient mode as well. But results are same as the temperature contours which initially developed on the body remain same and the iterations on further converge those results like wven in trainsient, I am unable to control the time for which the air is flowing over the body. And when I do the FSI, the analysis time it shows is 1 second which I am assuming is flow time of air over the body. Transient analysis gives the same results only soure time changes if I try to change the flow time.<\/p>\n<p>Help needed from the experts.<\/p>\n","protected":false},"template":"","class_list":["post-295058","topic","type-topic","status-closed","hentry","topic-tag-conjugate-heat-transfer","topic-tag-fsi","topic-tag-transient"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["289347","199","199842"],"_bbp_author_ip":["23.217.200.46"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1317"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["295058"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","199842","289347"],"_bbp_voice_count":["3"],"_bbp_reply_count":["25"],"_bbp_last_reply_id":["296101"],"_bbp_last_active_id":["296101"],"_bbp_last_active_time":["2023-08-02 12:39:16"]},"test":"menastap01gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/295058","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\/295058\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=295058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
