There are three pieces, one is the solid gyroid wall, and two are the hot and cold fluid domains. Because I need to simplify the model and reduce the CFD running time, I need to use the representative volume element (REV) piece and apply the periodic boundary conditions. I used SpaceClaim to prepare the three pieces separately. The workflow I am using in the FLuent mesh is the Fault-tolerance workflow because the gyroid&#8217;s STL file is inaccurate. However, I am not able to find how to define the periodic boundary condition. Anyone can help me with that even with a different workflow?<\/p>\n<p>&nbsp;<\/p>\n<p>Best regards,<\/p>\n<p>Sean <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/29-03-2024-1711675965-1.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-359561","topic","type-topic","status-closed","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["77643","199"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["727"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["359561"],"_bbp_forum_id":["27784"],"_bbp_engagement":["199","77643"],"_bbp_voice_count":["2"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["361025"],"_bbp_last_active_id":["361025"],"_bbp_last_active_time":["2024-04-08 09:04:16"]},"test":"sean-gaoutexas-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/359561","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\/359561\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=359561"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
