I&rsquo;ve also included bearings and a dynamic sealing in the setup.&lt;\/p&gt;&lt;p&gt;In the colder areas, I&rsquo;m using a conformal mesh. I&rsquo;ve already checked all the boundary conditions, and none of them show negative temperatures or anything unusual.&lt;\/p&gt;&lt;p&gt;I&rsquo;m simulating with a constant oil density of 1060 kg\/m&sup3;, which is quite high. For the dynamic viscosity, I&rsquo;ve defined a temperature-dependent expression (e.g., 0.0848 kg\/m&middot;s at 15 &deg;C). This property is already implemented as an expression. I&rsquo;ve left the air properties at their default values.&lt;\/p&gt;&lt;p&gt;Is there any other information I should provide to make my setup clearer?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394561","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/394561","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/394561\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=394561"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
