When the next DPM starts, it repeats Steps 1 to 3.   It should be noted here that the particles are tracked unsteady, like a real unsteady calculation, because the data at each time is not stored. Each particle state cannot be displayed. If there be the cause, in most cases, we recommend that you also calculate a non-stationary flow field. <\/p>\n<p>Attachments:<br \/>\n1. <a href=https:\/\/ansys13.ansys.com\/KnowledgeArticles\/Phase-1\/2043362\/2043362.pdf>2043362.pdf<\/a><\/p>\n","protected":false},"template":"","class_list":["post-166218","topic","type-topic","status-publish","hentry","topic-tag-fluent","topic-tag-fluid-dynamics","topic-tag-mp-particle-tracking","topic-tag-multiphase","topic-tag-other","topic-tag-transient"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"For a steady-state flow with non-stationary particles (DPM), the calculation summary is as follows: 1.Particles are injected at the set repeat interval in Interaction column, starting an unsteady calculation of the particle only. 2.The trajectory of the particles is calculated upto Particle Time Step Size \u00d7 Number of Time steps. 3.If the time is greater\" \/>\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<link rel=\"canonical\" href=\"https:\/\/innovationspace.ansys.com\/knowledge\/forums\/topic\/how-do-the-calculations-work-in-a-steady-state-flow-with-unsteady-dpm-analysis\/\" \/>\n\t<meta name=\"generator\" content=\"All in One SEO (AIOSEO) 4.9.10\" \/>\n\t\t<meta property=\"og:locale\" content=\"en_US\" \/>\n\t\t<meta property=\"og:site_name\" content=\"Ansys Knowledge | Ansys Innovation Space\" \/>\n\t\t<meta property=\"og:type\" content=\"article\" \/>\n\t\t<meta property=\"og:title\" content=\"How do the calculations work in a steady-state flow with unsteady DPM analysis?
