Do you mean how much of the cell is DPM? I think my case is a bit weird because my continuous phase is just made up of 100% evaporated particles.&lt;\/p&gt;&lt;p&gt;I was able to lower the tracking from 50,000 to 1,500 and decrease the time step size to 3e-4, which seems to stop particles from building up, but now k and epsilon residuals keep spiking and falling back down again after all other residuals have leveled off. Should I try a different turbulence model?&lt;\/p&gt;&lt;p&gt;In terms of LWF, should I turn that on in addition to the rest of my model? It&rsquo;s unclear what you mean by LWF should be sufficient, as the placement of the injectors matches up with a physical machined injector, and it seems adding LWF will just complicate the model further. Also I&rsquo;m not sure if LWF makes sense because at those temps won&rsquo;t the injected fuel vaporize into a gas?&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-377468","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/377468","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":4,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/377468\/revisions"}],"predecessor-version":[{"id":377474,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/377468\/revisions\/377474"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=377468"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
