I understand that i have to create a geometry 3D model, or in my case import one because i&acute;m using a real model of an aorta, so I import a STL file. This model has no holes for the &#8220;tube&#8221; so i create them splicing with a cuting plane. Then, due to the complexity of the model, to be able to make the mesh I use the autoskin methods, thus i can make the mesh automatically. Now when i did that a face a problem, when I open the next step, setup, the program shows this ERROR: This appears to be a surface mesh. So i decided to make the model solid in SpaceClaim, but know i face this problem of obsolete mesh and failed mesh. By the way im using Fluent, i saw some works using CFX but CFX in the mesh creation so i changed to Fluent, i guess is okey. What i want to do is just to set the mesh propertly and in the setup place the boundry conditions simply just to make a simulation completly, and then use a full model of subclavias and carotides.&nbsp;<\/p>\n<p>If you have a step by step tutorial or some tricks or clues for my problem I would apreciate it, I dont know if the problem is in the student version, the stl file.&nbsp;<\/p>\n<p>Thanks a lot. <img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/07-03-2024-1709812000-Captura de pantalla 2024-03-07 124616.png\" alt=\"Obsolete Mesh and failed mesh. \"><\/p>\n","protected":false},"template":"","class_list":["post-355870","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["73553","13659"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["465"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["355870"],"_bbp_forum_id":["27792"],"_bbp_engagement":["13659","73553"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["356100"],"_bbp_last_active_id":["356100"],"_bbp_last_active_time":["2024-03-08 15:15:21"]},"test":"m-escudero-2020alumnos-urjc-es"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355870","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\/355870\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=355870"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
