Can you try a different core count?&nbsp;&lt;\/p&gt;&lt;p&gt;Have you tried running double precision?&lt;\/p&gt;&lt;p&gt;Also, which MPI are you using (Intel MPI? Platform MPI?). Have you tried with a different MPI?&nbsp;&lt;\/p&gt;&lt;p&gt;You can use the *CONTROL_MPP_IO_LSTC_REDUCE keyword to get the same results with different MPI. Here is what the user manual says:&lt;\/p&gt;&lt;p&gt;&#8221;For numerical consistency, LSTC_REDUCE was developed to ensure a deterministic&lt;br&gt;summation order. This keyword gives identical results while using&lt;br&gt;the same decomposition and core counts but different MPI algorithms.&#8221;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;You can download the LS-DYNA manuals here:&lt;\/p&gt;&lt;p&gt;https:\/\/lsdyna.ansys.com\/manuals\/&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Let me know how it goes.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Reno.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-251494","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/251494","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\/251494\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=251494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
