Since the actual length would require computar capabilities not available, I decided to run periodic analysis. However, everytime when I try to create the periodic zones, the following message appears:<\/p>\n<p>warning: number of elements does not match between zone 6 and 7. <\/p>\n<p>error: failed to make zones periodic. <\/p>\n<p>error object: #f<\/p>\n<p>I am sure that both opposite sides of the tube (inlet and outlet) are identical. I say this because they are mirroed sides. Yet, I still get this message. I have changed multiple parameters but still get the same error.<\/p>\n<p>I have also read many post here, on cfd.com and researchgate. I have even tried face matching control. No success. <\/p>\n<p>Any clue on what should I do or extra material that I could read and get a possible solution for this? <\/p>\n<p>I have attached an image of my geometry. <\/p>\n<p>Thanks in advance<\/p>\n<div data-embedjson=\"{&quot;url&quot;:&quot;\/forum\/wp-content\/uploads\/forum-uploads\/805\/1DRJROV498BF.png&quot;,&quot;name&quot;:&quot;ansys forum.png&quot;,&quot;type&quot;:&quot;image\/png&quot;,&quot;size&quot;:188673,&quot;width&quot;:1624,&quot;height&quot;:2128,&quot;embedType&quot;:&quot;file&quot;}\">\n<a href=\"\/forum\/wp-content\/uploads\/forum-uploads\/805\/1DRJROV498BF.png\" download aria-label=\"ansys forum.png\"><br \/>\nansys forum.png<br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-163845","topic","type-topic","status-closed","hentry","topic-tag-error-object-f","topic-tag-numberofelementsdoesnotmatch-1","topic-tag-Periodicboundarycondition-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":["4585"],"_bbp_likes_count":["0"],"_bbp_subscription":["252974"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["163845"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","178854"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["197251"],"_bbp_last_active_id":["197251"],"_bbp_last_active_time":["2021-11-23 16:08:32"]},"test":"humbertosantos"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/163845","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\/163845\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=163845"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
