I am rotating the cube in the center counterclockwise at 5 rpm. When I preview the mesh motion, I can see that no remeshing is taking place. The first layer of cells stretches and deforms until there is negative cell volume, throwing an error. I am confused as to why the mesh is not remeshing when the cell parameters reach what I have inputted into the dynamic mesh settings. I have attached my dynamic mesh setup as well as a pre-mesh and post-error mesh image. Any help would be greatly appreciated!&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/08-10-2024-1728395470-pre-mesh.PNG\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-388556","topic","type-topic","status-answered","hentry","topic-tag-dynamic-mesh","topic-tag-moving-deforming-mesh-2","topic-tag-negative-cell-volume","topic-tag-remeshing","topic-tag-smoothing"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["467135","13659"],"_bbp_author_ip":["70.61.10.100"],"_btv_view_count":["569"],"_bbp_topic_status":["answered"],"_bbp_topic_id":["388556"],"_bbp_forum_id":["27792"],"_bbp_engagement":["13659","467135"],"_bbp_voice_count":["2"],"_bbp_last_reply_id":["389109"],"_bbp_last_active_id":["389109"],"_bbp_last_active_time":["2024-10-10 14:37:17"]},"test":"jwynnearielcorp-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/388556","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\/388556\/revisions"}],"predecessor-version":[{"id":389110,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/388556\/revisions\/389110"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=388556"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
