My understanding is that the solver has always been limited to using physical cores when using Mechanical (static problems etc). I am doing explicit analysis which uses the AUTODYN solver, and can easily be distributed across multiple cores. I have always used hyper-threading for explicit and get around 30% increase in performance when doing so (I have tested this extensively). I was just wondering why ANSYS have now blocked the MPI (at least, blocked it on the AUTODYN solver) as I lose that extra 30% performance, which is a lot when simulations run for 5+ hours.<\/p>\n","protected":false},"template":"","class_list":["post-55334","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/55334","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\/55334\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=55334"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
