(system exception: vector too long)  Linux:        SEVERE        Operation failed. (System exception: vector::_M_default_append)  This indicates that one of the zones is too large to be opened in CFD-Post.  A workaround for this issue is to split the largest zone. This can be done in Fluent with the Domain > Zones > Separate > Cells &#8230;  command.  The steps are: 1) create register to be used for separating the cell zone, i.e. by coordinate-direction 2) separate cell zone 3) save cas &#038; dat, export cdat for CFD-Post 4) open cdat in CFD-Post<\/p>\n","protected":false},"template":"","class_list":["post-164608","topic","type-topic","status-publish","hentry","topic-tag-2020-r2","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  20:20:55"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["1152"],"siebel_km_number":["2063202"],"product_version":["2020 R2"],"km_published_date":["2020-08-24T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["CFD-Post"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/164608","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\/164608\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=164608"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
