Therefore i am using ANSYS Mechanical thermal-electric. I Introduced Joule heat to calculate the heating effects of my terminals and connections. Due to oxidation, there is a oxide layer at the terminal (red lines in picture) producing a ohmic resistance. Now i want to calculate the power loss\/ heat generation due to the Ohmic resistance. (Ohmic resistance is measured and a constant value)<\/p>\n<p>As i inserted Joule heating in my model, i cannot create an electric contact conductance. <\/p>\n<p>I thought about adding a very thin solid, adding a heat generation (current^2*ohmic resistance) but then i have an additional joule heating in the solid because of the current flow.<\/p>\n<p>Is there another way to define a heat generation\/ contact resistance between two surfaces?<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/441\/4HZC0TI7KCGV.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/441\/4HZC0TI7KCGV.png\" alt=\"terminal.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-163234","topic","type-topic","status-closed","hentry","topic-tag-mechanical","topic-tag-thermal-electric","topic-tag-thermal-resistance-1"],"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":["2164"],"_bbp_likes_count":["0"],"_bbp_subscription":["251509"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["163234"],"_bbp_forum_id":["27791"],"_bbp_engagement":["20905","228332"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["195278"],"_bbp_last_active_id":["195278"],"_bbp_last_active_time":["2021-10-27 18:10:28"]},"test":"maurice-gonsergooglemail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/163234","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\/163234\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=163234"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
