The duct geometry (wall) was imported from the fluent case.file in alignment with the imported rocky export from fluent.&lt;\/p&gt;&lt;p&gt;The CFD coupling started after all particles were successfully loaded and settled in the container with NO particles passing or falling through geometries (walls).&lt;\/p&gt;&lt;p&gt;I appreciate any thoughts of that reported issues on particles reentered the cfd domain with what and why.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-459079","topic","type-topic","status-publish","hentry","topic-tag-cfd-dem","topic-tag-rocky-dem-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["459079"],"_bbp_subscription":["603308","66199"],"_bbp_author_ip":["139.86.69.39"],"_bbp_last_reply_id":["459210"],"_bbp_last_active_id":["459210"],"_bbp_last_active_time":["2026-06-02 18:15:29"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["603308","66199"],"_btv_view_count":["78"],"_bbp_topic_status":["unanswered"]},"test":"baocong-jingunisq-edu-au"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/459079","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\/459079\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=459079"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
