A usual remedy is to increase the &#8220;Max. Number of Steps&#8221; in Tracking Parameters of DPM setup to follow the particles for a longer distance. If this does not change the fate of the particles, a deeper look at the particle velocities may explain why an increase of integration steps would not help. If, for example, the relative velocity between the mill walls of a stirrer and the particles is almost zero, the fate of these particles will remain incomplete. Another possible reason is that the particles are stuck in the recirculation zone.<\/p>\n","protected":false},"template":"","class_list":["post-161851","topic","type-topic","status-publish","hentry","topic-tag-16-2","topic-tag-dpm","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-mp-particle-tracking","topic-tag-multiphase","topic-tag-other"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_forum_id":["27809"],"_bbp_author_ip":["23.56.168.180"],"_bbp_last_active_time":["1-24-2023  20:20:15"],"_btv_view_count":["1027"],"siebel_km_number":["2040676"],"product_version":["16.2"],"km_published_date":["2015-12-08T01:23:32.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/161851","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/161851\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=161851"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
