This geometry is composed of many triangles and, as it is normal, it is not smooth at all.<\/p>\n<p>When I try to generate a mesh for CFD, I can not generate a mesh that is well enough, and when I simulate the case, I see that in a couple of areas there are a few elements that have abnormal values for the velocity. This is clearly because of the mesh. I tried to refine it, or employ some methods such as inflation to the walls, but it could not create a mesh, I suppose due to the large number of triangles that describe the surface.<\/p>\n<p>So, the question is this; Is there a way that I can approach this kind of situation to generate a mesh that is good?<\/p>\n<p>Sorry for the vagueness of the question, if anybody can help, I will be happy to share the specifics that are needed.<br \/>Thank you!!<\/p>\n","protected":false},"template":"","class_list":["post-309915","topic","type-topic","status-closed","hentry","topic-tag-mesh","topic-tag-stl"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["293396","240"],"_bbp_author_ip":["23.52.43.88"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["346"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["309915"],"_bbp_forum_id":["27790"],"_bbp_engagement":["240","293396"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["310426"],"_bbp_last_active_id":["310426"],"_bbp_last_active_time":["2023-10-06 16:22:14"]},"test":"mech02376uowm-gr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/309915","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\/309915\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=309915"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
