I have a requirement for excluding the mesh motion in a deforming boundary. As this does not seem to be directly available, is it somehow possible to patch the boundary velocities of the deforming surface to zero ? In a UDF ?nThe reason I want this is because I have a rigid body boundary moving very close and parallel to a stationary surface. I do not wish to expend the cost of tiny cells in order to resolve the gap between the boundaries, so want to approximate the situation by having them touch. I think this is analogous to the approximation of turbomachinery touching the shroud. However, turbomachinery has the luxury of not needing dynamic meshing.n<\/p>\n","protected":false},"template":"","class_list":["post-51474","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23744"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["*\u000b??\u0000\u0001\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0001"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1474"],"_bbp_subscription":["231409"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["51474"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","183887","184487"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["140001"],"_bbp_last_active_id":["140001"],"_bbp_last_active_time":["2021-01-26 00:17:58"]},"test":"danbence"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/51474","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\/51474\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=51474"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
