I believe what&#8217;s happening is that nothing is preventing the gas from continuing to be adsorbed, leading to heat release and a pressure increase inside the tank after the switch. I&rsquo;ve noticed an abnormal rise in both the adsorption mass and temperature in the tank, which could be related to the reversed flows at the inlet. I&#8217;d also expect the system to reach equilibrium at some point, but this hasn&#8217;t happened even after several hundred time steps. I&rsquo;m wondering if there is an option to force the solver to account for this.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-390058","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/390058","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\/390058\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=390058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
