Now i add a discret phase model (DPM) with unsteady Partikel tracking (two-way). My particle material ist water-liquid as Inert. Surface injection with a mass flow rate of 0.06 kg\/s and an velocity of 47.4 m\/s.<\/p>\n<p><\/p>\n<p>I need to activate unsteady paticle tracking because I would like to have wall-film activated on my wall. This option is only available if unsteady paticle tracking is selected. <br \/>Now Fluent would like to have injection times start time \/ stop time. I left them at zero. <\/p>\n<p>My first question: <br \/>I want a steady state simulation what exactly should I enter as start and stop time? <\/p>\n<p>My problem is that particles are tracked but no particles escape or remain incomplete. All values are set to 0, so it is not possible to export the particle history file.<\/p>\n<p><\/p>\n<p>Why are no particles injected? <\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Comand bar:<\/p>\n<p><\/p>\n<pre>\"Advancing DPM injections ....<\/pre>\n<p><\/p>\n<pre style=\"-qt-block-indent: 0; text-indent: 0px; margin: 0px;\">number tracked = 36, escaped = 0, aborted = 0, trapped = 0, evaporated = 0, incomplete = 0, incomplete_parallel = 0\"<\/pre>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>thanks in advance.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-31271","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3443"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["1843"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31271"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","160068","180497"],"_bbp_voice_count":["3"],"_bbp_reply_count":["20"],"_bbp_last_reply_id":["125101"],"_bbp_last_active_id":["125101"],"_bbp_last_active_time":["2020-08-21 16:11:06"]},"test":"lokman61"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31271","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\/31271\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31271"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
