My flow domain consists of a large rectangular domain representing the surrounding air of the turbine and the turbine geometry which is located in a circular domain in the center of the large domain. I want the turbine to rotate by using a sliding mesh between both flow domains.&lt;\/p&gt;&lt;p&gt;So far, I imported my geometry in DesignModeler and prepared it to get two seperate surfaces and assigned named selections to inlet, outlet, walls etc. I also created\/named one interface at the stationary domain around the turbine and one interface to the rotating part.&lt;br&gt;Now, I want to create the mesh with Fluent-Meshing 2D Meshing Workflow but am getting the error, that &#8220;&lt;span style=&#8221;color: #000000;&#8221;&gt;More than one meshing part is identified. Perform share Topology in geometry and try again.&#8221;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;color: #000000;&#8221;&gt;I have already done that Share Topology once and was successful in creating the mesh. But in Fluent solver, I wasn&#8217;t able to create a mesh interface. In the boundaries section, Fluent created a combination of my two interfaces and an additional shadow-version of this combination, both assigned as walls without the option to change to interface.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;color: #000000;&#8221;&gt;Is it possible to create a 2D mesh in Fluent-Meshing without the Shared Topology to keep the interfaces created previously?&lt;br&gt;Hope, there is any chance out there to get it done this way.&lt;br&gt;Thanks,&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;color: #000000;&#8221;&gt;Lennard&lt;\/span&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-460403","topic","type-topic","status-publish","hentry","topic-tag-2d","topic-tag-fluent-meshing","topic-tag-mesh-interfaces"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["460403"],"_bbp_subscription":["702911"],"_bbp_author_ip":["195.37.177.70"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["460403"],"_bbp_last_active_time":["2026-06-26 10:45:20"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["702911"],"_btv_view_count":["13"],"_bbp_topic_status":["unanswered"]},"test":"ljoasstud-hs-bremen-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/460403","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\/460403\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=460403"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
