I made my geometry in Solidworks, and it has four parts (tank, shaft, impeller, and rotating zone around the impeller). Originally, my tank had a lid which gave me issues using the Share Topology function on the interface of the hole where the shaft went through. I ended up just taking the lid off the tank to avoid those issues. When I examine the lid-less model in SpaceClaim, it doesn&#8217;t show any coincident topology, so I can&#8217;t use the Share or Force Share functions, but when I try to mesh it in Fluent, it insists that there is coincident topology, but when I try to apply the Share Topology function in the Fluent mesher, I get this error:n462 self-intersecting triangles exist in the model, which is above the limit for automatic smoothing ( 10 ).Either CAD plug-ins (instead of CAD readers) were used, which sometimes lead to a Multi-body-part topology, or Share Topology in SCDM\/DM failed at certain locations. In the latter case, make sure to invoke Forced Share option in SCDMnThis is my first model in Fluent so I have no idea how to fix this! I have run this model both on my university&#8217;s virtual computer lab so on the university&#8217;s license, and on a student version I downloaded and had the same issues each time. Both the Solidworks geometry model and ANSYS Workbench are version 20 so I don&#8217;t think that&#8217;s the issue either, and the Solidworks model was uploaded to Fluent as a STEP file.nThank you so much!nn<\/p>\n","protected":false},"template":"","class_list":["post-53607","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["25928"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["D???"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["10388"],"_bbp_subscription":["233395","19672","2627"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["53607"],"_bbp_forum_id":["27792"],"_bbp_engagement":["62","199","2627","19672","187596"],"_bbp_voice_count":["5"],"_bbp_reply_count":["12"],"_bbp_last_reply_id":["314592"],"_bbp_last_active_id":["314592"],"_bbp_last_active_time":["2023-11-02 15:02:28"]},"test":"asendero"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53607","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/53607\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=53607"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
