The line can be defined either as a cut line, taking the result values directly at the element faces. With that option the chart plot is smooth and reasonable. The second option is defining the line as a sample line. The result values are interpolated to a certain number of sample points specified with the line definition. There is a tolerance set under Edit > Options > CFD Post called Interpolation Tolerance.  The default value is 0.5 which is 0.5% of the domain extents.  This might not be fine enough in every case. Setting this value to a smaller number has resolved the anomaly in the chart plot.<\/p>\n","protected":false},"template":"","class_list":["post-164648","topic","type-topic","status-publish","hentry","topic-tag-4424","topic-tag-cfd-post","topic-tag-fluid-dynamics","topic-tag-general"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3-15-2023  20:20:35"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["880"],"siebel_km_number":["655619"],"product_version":["16"],"km_published_date":["2007-08-29T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["CFD-Post"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164648","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164648\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164648"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
