I have attached the model below for reference. As can be seen, the model is completely hollow, accurately depicting the true geometry of the aortic arch. In tutorials that I have watched to guide me through the process, each of the models showed only the inner surface of the wall, as well had closed inlet\/outlet faces that could be selected as named selections. My question that stems from this is, how do I create named selections based on the geometry I currently have? Do I need to modify the geometry to only show the inner wall, and likewise have faces that can be selected for the inlets and outlets that I need? Or is there a way to run the simulation properly by performing different steps from where I am currently at? n<img src=\/forum\/wp-content\/uploads\/forum-uploads\/795\/7U1JGFTPFXCN.png width=1826 height=866 \/>nn<\/p>\n","protected":false},"template":"","class_list":["post-54738","topic","type-topic","status-closed","hentry","topic-tag-ansys-fluent","topic-tag-ansys-student","topic-tag-cfd","topic-tag-mesh"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["27074"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["DI|?"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1320"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["54738"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","188783"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["150943"],"_bbp_last_active_id":["150943"],"_bbp_last_active_time":["2021-04-27 14:34:34"]},"test":"jcm169"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/54738","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\/54738\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=54738"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
