Also, I made these parts as one part (form a new part).&nbsp;<\/div>\n<div>In meshing, I generated the mesh directly after that I began to modify it by trying several options (sizing, inflation,&#8230;., etc.) as you can see in the picture. But, still can&#8217;t reach so good mesh quality (skewness &amp; orthogonal).<\/div>\n<div>My questions are:<\/div>\n<div>1- regarding the geometry, is there any difference if I make an extrude for a surface to create a fluid domain? or should all fluid domains created by making volumes?&nbsp;<\/div>\n<div>2- regarding the mesh, the tick sign in front of the geometry parts (see the red rectangle in the picture) is changing every time I make meshing, what is the reason?<\/div>\n<div>3- I&#8217;m asking you to help me do the best mesh for my case. Which mesh method and sizing should I select to enhance the mesh?<\/div>\n<div>&nbsp;<\/div>\n<div>Thank you.<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/12\/06-12-2023-1701847732-11.png\" alt=\"\"><\/div>\n","protected":false},"template":"","class_list":["post-326567","topic","type-topic","status-closed","hentry","topic-tag-3d-geomertry","topic-tag-extrude","topic-tag-fluid-volume","topic-tag-meshing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["43660","39507"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["391"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["326567"],"_bbp_forum_id":["27792"],"_bbp_engagement":["39507","43660"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["326658"],"_bbp_last_active_id":["326658"],"_bbp_last_active_time":["2023-12-06 14:22:56"]},"test":"hasan-mustafa-moayadstudent-uni-miskolc-hu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/326567","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\/326567\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=326567"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
