I am now running the newer model that has 29M cells and it is running fine but it us using ~120 GB of RAM. That means even with a pressure based SIMPLE solver with polyhedra cells it&#8217;s using 4GB\/1M cells which seems like a lot.&lt;\/p&gt;&lt;p&gt;I thought the recent Fluent versions only use 1-2 GB\/1M cells. Do you think it&#8217;s any issue with my hardware or the fluent parallel settings?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-362705","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/362705","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\/362705\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=362705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
