My setup has a floating body that is supposed to collide with a fixes structure, but as they get closer, there&rsquo;s always an artificial gap between them that&rsquo;s filled with the fluid mesh. This leads to a volume mesh error in my simulation.&lt;br&gt;Does anyone know how to avoid this problem? Or is it even possible to simulate contact between two bodies with the ICFD solver?&lt;br&gt;Any advice or ideas would be really appreciated!&lt;br&gt;Thanks!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394859","topic","type-topic","status-publish","hentry","topic-tag-collision","topic-tag-icfd-1","topic-tag-implicit-dynamics-1","topic-tag-numerical-instability-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["2607:f278:410e:5:b595:74ae:1e4f:caf3"],"_btv_view_count":["477"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["13937","273428","519630"],"_bbp_topic_id":["394859"],"_bbp_forum_id":["27814"],"_bbp_engagement":["13937","273428","519630"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["422810"],"_bbp_last_active_id":["422810"],"_bbp_last_active_time":["2025-02-21 17:45:46"]},"test":"behnenjhawaii-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/394859","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\/394859\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=394859"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
