I am trying to incorporate a rigid body motion via Layering, but I observe that the cells are being stretched instead of split for a column cells that are interfacing between 2 fluid zones (similar integration problem here:https:\/\/innovationspace.ansys.com\/forum\/forums\/topic\/problems-with-dynamic-mesh-settings-while-mesh-motion\/)&lt;\/p&gt;&lt;p&gt;I tried varying the split and collapse factors. Since the cells are collapsing but not splitting, I think the problem is related to how I set up the interior cell motion. From other documentation and tutorial videos, I think I need to specify a mesh interface between the two fluid zones, but I&#8217;m not able to conver the internal zones into a mesh interface. Do you have suggestions on this? Thank you again so much!&lt;\/p&gt;&lt;p&gt;Screenshots of inputs and sim case is below; averge cell height is 0.01m:&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/02\/04-02-2025-1738711011-mceclip0.png\" width=\"523\" height=\"235\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/02\/04-02-2025-1738711044-mceclip1.png\" width=\"552\" height=\"224\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/02\/04-02-2025-1738711185-mceclip3.png\" width=\"281\" height=\"205\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/02\/04-02-2025-1738711158-mceclip2.png\" width=\"205\" height=\"204\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-408399","topic","type-topic","status-answered","hentry","topic-tag-dynamic-mesh","topic-tag-fluent","topic-tag-layering","topic-tag-transient"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["408399"],"_bbp_subscription":["295638","13659"],"_bbp_author_ip":["128.61.187.37"],"_bbp_last_reply_id":["408969"],"_bbp_last_active_id":["408969"],"_bbp_last_active_time":["2025-02-09 21:27:23"],"_bbp_reply_count":["7"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["295638","13659"],"_btv_view_count":["1086"],"_bbp_topic_status":["answered"]},"test":"zoelle-wonggatech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/408399","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/408399\/revisions"}],"predecessor-version":[{"id":408827,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/408399\/revisions\/408827"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=408399"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
