I have created a suitable 3D model in a previous software, here I have already labeled all the significant surfaces like inlet, outlets and the wall. I now wnat to load the model into discovery to create a volume body and optimize the STL file. The problems I&#8217;m facing are the following:&nbsp;&lt;\/p&gt;&lt;p&gt;1) If I optimize my mesh in Discovery it seems like a second surface is created over the original STL which leads to problems in the following software (Ansys Fluent)&lt;\/p&gt;&lt;p&gt;2) All the tutorials I have watched have a 3D model which is not seperated into tiny STL triangles but is rather consisting of &#8216;normal&#8217; surfaces which is also a problem I can&#8217;t seem to fix, do I just need to tweak my view mode or is there indeed no continous surface?&nbsp;&lt;\/p&gt;&lt;p&gt;3) I feel like because of the afore mentioned problems I cannot load my STL from Discovery to Fluent properly, I always get errors when trying to do the capping step in the Fault Tolerant workflow as there seems to be a problem with the outlines of my defined outlets\/inlets&nbsp;&lt;\/p&gt;&lt;p&gt;I don&#8217;t know if this is enough information to go on but I would appreciate some help and will provide further information if necessary.&nbsp;&lt;\/p&gt;&lt;p&gt;Kind regards&lt;\/p&gt;&lt;p&gt;Schmid&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-440552","topic","type-topic","status-publish","hentry","topic-tag-3d-mesh","topic-tag-ansys-discovery","topic-tag-ansys-fluent","topic-tag-file-loading","topic-tag-naming-surfaces-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27789"],"_bbp_topic_id":["440552"],"_bbp_subscription":["590762","199842","199","594589"],"_bbp_author_ip":["212.201.7.60"],"_bbp_last_reply_id":["440649"],"_bbp_last_active_id":["440649"],"_bbp_last_active_time":["2025-09-03 08:05:23"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["1"],"_bbp_voice_count":["3"],"_btv_view_count":["8034"],"_bbp_topic_status":["unanswered"],"_bbp_engagement":["199","199842","590762"]},"test":"thore-schmidges-thm-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/440552","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\/440552\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=440552"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
