Check it and run some iterations \/ time steps so that a DPM iteration is done and see whether it helps.  To diagnose the efficiency of the utilisation of the CPU resources, type the following into the TUI window at the prompt: (rpsetvar &#8216;dpm\/verbosity 3) (dpm-parameters-changed)  Run enough iterations \/ time steps to get through at least one DPM iteration.  Note that this diagnostic can have a small adverse effect on performance, so you may want to switch the DPM verbosity back to 1 once your tests are complete.. (Remember to issue `(dpm-parameters-changed)\u00b4 again for the change to take effect.) Also, the speed-up it may contribute depends very much on the individual situation, involving both the simulation problem setup and the hardware configuration used.<\/p>\n","protected":false},"template":"","class_list":["post-161821","topic","type-topic","status-publish","hentry","topic-tag-19-2","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-modeling-setup-advice","topic-tag-mp-particle-tracking","topic-tag-multiphase"],"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  20:20:21"],"_btv_view_count":["1659"],"siebel_km_number":["2056286"],"product_version":["19.2"],"km_published_date":["2018-09-05T01:37:49.000Z"],"family":["Fluid Dynamics"],"application_name":["FLUENT"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/161821","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\/161821\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=161821"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
