Picture 2: y-velocity data plot in point of interest. Picture 3: comparison of y-velocity from ANSYS FLUENT and LS-DYNA ICFD solver. Picture 4: y-velocity contour plot, comparison between colour in plot on point of interest and legend).<\/p>\n<p><\/p>\n<\/p>\n<p>I am currently running a &quot;benchmark&quot; iCFD problem (flow around a cylinder) using LS-DYNA, for Re = 0.5. I am interested in the y-velocity at a point 8 diameters from the cylinder (see pictures below).<\/p>\n<p>When I extract the dataplot from this point, you can see that the velocity is 6e-4 m\/s. When I compare this result to the contourplot, however, you can see that the color where the point is situated belongs more to the 2.5e-4 m\/s y-velocity. <\/p>\n<p>When comparing the LS-DYNA answer to the FLUENT answer, it is clear that indeed the y-velocity should be much lower than 6e-4 m\/s. So why does the dataplot give me a different result, and how can I get the right result?<\/p>\n<p>Kind regards,<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/442\/APPSTOPR6TDS.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/442\/APPSTOPR6TDS.png\" alt=\"vel_magnitude_with_point.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-158251","topic","type-topic","status-closed","hentry","topic-tag-ansys-fluent","topic-tag-cfd","topic-tag-fluids","topic-tag-ls-dyna"],"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":["502"],"_bbp_likes_count":["0"],"_bbp_subscription":["122799"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158251"],"_bbp_forum_id":["27792"],"_bbp_engagement":["178074","183162"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["177850"],"_bbp_last_active_id":["177850"],"_bbp_last_active_time":["2021-05-17 07:33:46"]},"test":"lcp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158251","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\/158251\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
