This indicates that the partitioning is not encapsulating the wedge\/prism columns and therefore due to cell quality reason this makes it difficult to do surface remeshing AND extrusion since the extruded prism\/wedge columns of cells don&#8217;t reside on one CPU\/core.     Remeshing when prism\/wedge column of cells are not encapsulated may ultimately lead to negative cells and hence the message:  &#8220;prism columns not encapsulated, can&#8217;t remesh&#8221;:  The solution to overcome this warning message is to choose a partitioning method that ensures columns of prism\/wedge cells to be encapsulated\/reside on a CPU\/core. Here is a note from Fluent User Documentation:  In parallel, a partition method that partitions perpendicular to the extrusion surface should be used. For example, if the normal of the extrusion surface points in the X-direction then Cartesian-Y or Cartesian-Z would be the perfect partition methods.<\/p>\n","protected":false},"template":"","class_list":["post-171125","topic","type-topic","status-publish","hentry","topic-tag-4431","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-mesh-deformation","topic-tag-moving-deforming-mesh"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["2\/6\/2023 20:20"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["409"],"siebel_km_number":["2042450"],"product_version":["17"],"km_published_date":["2016-06-09T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/171125","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\/171125\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=171125"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
