I&#8217;ve done this before with a coarser mesh, where refinement normal to the wall was not added. However for the case below, I get the following error: &#8220;Corrupted double-linked list; received signal SIGSEGV&#8221;. I found that the deforming mesh-interface (def-meshintf1) and the motion of zone2. Other internal dynamic mesh boudnaries converge. Would forcing the entire domain to be structured cells potentially fix this problem? I have also attached the boundary conditions that I am specifying to clarify. Thank you again so much!&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/05\/28-05-2025-1748467544-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/05\/28-05-2025-1748467192-blobid0.png\" alt=\"image\" width=\"441\" height=\"775\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-432785","topic","type-topic","status-publish","hentry","topic-tag-fluent-ansys-1","topic-tag-fluent","topic-tag-fluent-mesh","topic-tag-layering"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["432785"],"_bbp_subscription":["295638","13659"],"_bbp_author_ip":["128.61.160.57"],"_bbp_last_reply_id":["432996"],"_bbp_last_active_id":["432996"],"_bbp_last_active_time":["2025-05-30 20:55:17"],"_bbp_reply_count":["5"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["295638","13659"],"_btv_view_count":["132"],"_bbp_topic_status":["unanswered"]},"test":"zoelle-wonggatech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/432785","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\/432785\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=432785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
