Probably the fact is that the thickness of these bodies is 0.3 mm which is smaller than the element size used for meshing. But a reduction in the element size creates doen&#8217;t provide any solution due to the elevated number of nodes. Thus, I want to create multiple elements within the wall of the bodies, but since the geometry is quite complex mesh sweeping doesn&#8217;t work (if I select manually the source it keeps to be yellow, unselected) and to create a midsurface I&#8217;ve tried to use virtual cells (virtual topology) by merging all the external faces in one and all the internal faces in the opposite one in order to apply a sweepable mesh, but no chances to work (see image).<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/126bdb0d-9b87-4063-acfd-aa9500effb47\/d45c2c8e-ec0e-44ed-969e-aaf700c41d37_failed-sweep-virtual-topology.jpg?width=690&amp;upscale=false\" alt=\"failure during sweeping mesh of virtual cells\"><\/p>\n<p><\/p>\n<p>Any other tips to solve this issue and get a proper deformation?<\/p>\n<p><\/p>\n<p>Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-38670","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["10848"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["3539"],"_bbp_subscription":["241639"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["38670"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","167024"],"_bbp_voice_count":["2"],"_bbp_reply_count":["17"],"_bbp_last_reply_id":["98083"],"_bbp_last_active_id":["98083"],"_bbp_last_active_time":["2019-11-08 14:49:23"]},"test":"nyla"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/38670","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\/38670\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=38670"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
