I have used Ansys for many years and I have done Ansys Discovery conjugate heat transfe for so many times. But this simple simulation is just NOT WORKING. The issue is it is not generating the automatic contacts from the Region Interface Generator. When trying to updated it is inactive. If I change the tolerance it updates but then no contact is generated. The fluid is air, part of a fluid physics reagons, the &#8220;cubes&#8221; are solids, part of another Thermal Physics Region. I have tried everything over the last few days to solve this mistery, even found a forum on here \/forum\/forums\/topic\/region-interface-generator-does-not-generate-interface-between-fluid-solid\/ , which actually doesn&#8217;t solve any problem as nothing from there explanation which was half kept on a private chat doesn&#8217;t do anything. I have also tried to setup the contact manually, with no result. Does anyone have this problem as I&#8217;m beginning to believe this Ansys Discovery license is not capable of solving anythign rather that basic FEA problems!?<\/p>\n<p>&nbsp;<\/p>\n<p>Thanks in advance,<\/p>\n<p>Alin<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/23-02-2024-1708713454-p2.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-353554","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["42416","3452","340869","341047"],"_bbp_author_ip":["23.206.193.41"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["440"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["353554"],"_bbp_forum_id":["27792"],"_bbp_engagement":["3452","42416","340869"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["1"],"_bbp_last_reply_id":["356059"],"_bbp_last_active_id":["356059"],"_bbp_last_active_time":["2024-03-08 08:51:41"]},"test":"alin-risteaalristech-co-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/353554","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\/353554\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=353554"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
