I am running a simulation for a counterflow double pipe heat exchanger but the fluids in both the inner pipe and annulus should be fully developed so on a different file I made the boundaries periodic and wrote the x y z velocity profiles of the 2 fluids after running the simulation with the energy off in &#8220;models&#8221;. In the new file, in the setup, boundary conditions, I am choosing &#8220;velocity inlet&#8221; for the hot and cold inlets, and in the edit I am letting Ansys read the velocity profiles. I am choosing the hot inlet to be 433 K and cold inlet to be 403K. For both outlets I am choosing &#8220;outflow&#8221;. When I am running the simulation I am not getting a heat transfer between the fluids and walls and thus, it is not converging. What should I do to make it work?<img decoding=\"async\" title=\"velocity inlet\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/03\/08-03-2023-1678295036-11.png\" alt=\"\"> <img decoding=\"async\" title=\"velocity inlet temperature\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/03\/08-03-2023-1678295081-22.png\" alt=\"\"> <img decoding=\"async\" title=\"temperature contour \" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/03\/08-03-2023-1678295114-t.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-253132","topic","type-topic","status-closed","hentry","topic-tag-heat_exchanger-1","topic-tag-3d-components","topic-tag-fluidflowfluent-1","topic-tag-heat-transfer","topic-tag-Periodicboundarycondition-1","topic-tag-turbulent-flow","topic-tag-velocity","topic-tag-velocity-profile"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["277036","22555","199"],"_bbp_author_ip":["23.44.170.21"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["847"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["253132"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","22555","277036"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["253264"],"_bbp_last_active_id":["253264"],"_bbp_last_active_time":["2023-03-09 15:47:05"]},"test":"bassil-bassillau-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/253132","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\/253132\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=253132"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
