My problem is that after I run the simulation and I try to check the particle residence time, the particles didn&#8217;t show up. My injection start time is 0, and the stop time is 0.05, which is the same as my time step size (I want the particle inject only once) , the particle initial velocity is set as 0, I&#8217;m wonder if I do anything wrong? the following pictures are my screenshots of my simulation.<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706087304-20240124_volume injection problem2.png\" alt=\"\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706087381-20240124_volume injection problem1.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-346307","topic","type-topic","status-closed","hentry","topic-tag-dpm","topic-tag-dpm-concentration","topic-tag-dpm-tracking"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["337173","199"],"_bbp_author_ip":["23.52.43.16"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1001"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["346307"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","337173"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["346930"],"_bbp_last_active_id":["346930"],"_bbp_last_active_time":["2024-01-29 06:24:10"]},"test":"bill430325gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/346307","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\/346307\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=346307"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
