I have two models I am trying to simulate with different inlet areas which I will explain in detail to clarify my question.<\/p>\n<p class=\"_1qeIAgB0cPwnLhDF9XSiJM\">My first model has an inlet area of 602 mm^2 with a inlet velocity of 0.00000968992248 m\/s.<\/p>\n<p class=\"_1qeIAgB0cPwnLhDF9XSiJM\">My second model has an inlet area of 402 mm^2. My goal is to scale up model 2&#8217;s inlet to the the same inlet velocity as the 602 mm^2 inlet. Basically with my second model due to CAD restrictions my inlet size is stuck at 402 mm^2. I cannot increase it to match model 1. So since I cannot scale the dimensional size I would like input a velocity that would give me the same velocity\/area as model 1 so they are equal. Is this possible in ansys with a simple ratio formula ? Is there a way to calculate this new velocity so they both match and account for the scale up ?<\/p>\n<p class=\"_1qeIAgB0cPwnLhDF9XSiJM\">Thank you all for the help!<\/p>\n","protected":false},"template":"","class_list":["post-252625","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["251923","15180","199"],"_bbp_author_ip":["23.192.164.18"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["213"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["252625"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","15180","251923"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["252903"],"_bbp_last_active_id":["252903"],"_bbp_last_active_time":["2023-03-07 16:49:29"]},"test":"bb9561wayne-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/252625","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\/252625\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=252625"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
