Rotational periodic geometries are often simulated using only one segment. Sometimes a full model should be generated starting from the existing segment model. In Fluent this can be done by doing the following steps:<\/p>\n
<\/p>\n
1)Read in the segment case<\/p>\n
<\/p>\n
2)Rotate this segment by the number of degrees the segment has (Setting Up Domain -> Transform -> Rotate)<\/p>\n
<\/p>\n
3)Append the original segment case (Setting Up Domain -> Append -> Append Case File)<\/p>\n
<\/p>\n
4)Fuse the mesh nodes at the overlapping faces (Setting Up Domain -> Combine -> Fuse) 5)<\/p>\n
<\/p>\n
Repeat Step 2-4 until the full model is created.<\/p>\n
<\/p>\n
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&help). 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.<\/p>\n
<\/p>\n
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-54817","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/54817","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/54817\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=54817"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
