<p>You’re welcome, and thanks for starting a new topic for a new question. <\/p><p>1) Up to you – how high is the building relative to the ABL? What is upstream to decide if the ABL has formed or been chewed up by the scenery? <\/p><p>2) Your monitor shows a roughly repeated variation every 50-ish iterations. Plot velocity contrours around the building every 5 iterations. Also pressure on the building. What do they tell you?<\/p><p>3) How long a transient did you run? Time step was probably well under a second, but what frequency do you expect the flow to change at?<\/p><p>The extra data from 2 & 3 will help you decide if the flow changes enough to need to worry about it. A transient flow may be a very small fluctuation that can be ignored, or a very big change that can’t. <\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-350855","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/350855","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/350855\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=350855"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
