Sometimes a full model should be generated starting from the existing segment model. In Fluent this can be done by doing the following steps: <br \/> 1)Read in the segment case <br \/> 2)Rotate this segment by the number of degrees the segment has (Setting Up Domain -> Transform -> Rotate) <br \/>  3)Append the original segment case (Setting Up Domain -> Append -> Append Case File) <br \/>  4)Fuse the mesh nodes at the overlapping faces (Setting Up Domain -> Combine -> Fuse) <br \/>  5)Repeat Step 2-4 until the full model is created. <br \/> After reading in the original case the last time, two fuse operations are needed. If the periodic faces have no matching meshes you have to use non-conformal interfaces instead of the fuse command (Setting Up Domain -> Mesh\u2026) When appending a case file to an existing case with the same boundary names they will be automatically changed. You can avoid this by renaming the boundaries before appending a case. At the end you will have the boundaries as segments. You can unite them using Setting Up Domain -> Combine -> Merge.<\/p>\n","protected":false},"template":"","class_list":["post-157109","topic","type-topic","status-publish","hentry","topic-tag-ansys-fluent","topic-tag-periodic"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["06-06-2022 20:20"],"_bbp_forum_id":["27796"],"_btv_view_count":["3632"],"_bbp_likes_count":["1"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/157109","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\/157109\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=157109"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
