Because I need to determine the ideal sizing of the two bodies, I first run a mesh independence study for the large body without the small body embedded in it. From this, I determine the ideal sizing parameters (min\/max size of surface elements, max cell length of volume elements) in Fluent Meshing &#8211; Watertight Workflow. Then, I want to embed the smaller body in the larger body, and play with the mesh density of the smaller body to determine its ideal sizing. However, this is where I run into trouble. When I open my geometry (smaller body embedded in larger body) in Fluent Meshing, I define a &quot;body sizing&quot; for my smaller geometry and give in the sizing parameters for my larger body as previously determined. What I see now is that the mesh density of my larger body has changed, even though I didn&#039;t change the parameters. I don&#039;t understand what&#039;s going on. Below you can see two pics: the first one is the smaller body embedded in the larger one, but without defining a body sizing for the smaller body. In the second pic, I&#039;ve defined a body sizing for the smaller body, and you can see how the mesh density of the larger body has changed (even though the sizing parameters remained the same). Any ideas on how I can keep the original mesh density of my larger body?<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/623\/F8L532HOBI2X.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/623\/F8L532HOBI2X.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-164282","topic","type-topic","status-closed","hentry","topic-tag-fluent","topic-tag-meshing","topic-tag-solid-modeling","topic-tag-watertight-workflow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2774"],"_bbp_likes_count":["0"],"_bbp_subscription":["247130"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164282"],"_bbp_forum_id":["27790"],"_bbp_engagement":["16400","74635"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["198672"],"_bbp_last_active_id":["198672"],"_bbp_last_active_time":["2022-01-11 13:54:38"]},"test":"shadowfax7"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164282","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\/164282\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164282"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
