Now i want to implement these energy losses as a volumetric heat source in the middle grey layer of the FC and calculate the generated temperature in the solid regions. Below is a little example how the geometry can look like. To calculate the Temperature i want to connect the fluent model with a thermal transient model to calculate the temperature.<\/p>\n<p><\/p>\n<p>Is it possible to model the volumetric heat source of the thermal transient model with a calculated heat using udf in fluent??<\/p>\n<p><\/p>\n<p>I know that that it is possible to implement a function as a volumetric heat source, but i don&acute;t know how to use a function for heat source which is calculated in a udf in fluent.<\/p>\n<p><\/p>\n<p>Thanks for your help<\/p>\n","protected":false},"template":"","class_list":["post-40011","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["12190"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1580"],"_bbp_subscription":["245130"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["40011"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","170770"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["102628"],"_bbp_last_active_id":["102628"],"_bbp_last_active_time":["2020-01-15 11:32:51"]},"test":"michael104"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/40011","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\/40011\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=40011"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
