It&#8217;s usually a little slower and doesn&#8217;t scale well with number of processors selected, but if it doesn&#8217;t result in excessively long turn-around, I&#8217;d just continue using it.&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;I don&#8217;t know the internal logic used to decide where\/how to split the mesh for domain decomposition (~random, I&nbsp; suspect) and I don&#8217;t know of anyway to control that. I can see how you might hit the error for some models and not others.&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;I couldn&#8217;t find record of the error you reported after a cursory search in our records&#8230; you may be the first user to report it to us.&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;Best,&lt;\/div&gt;&lt;div&gt;Bill&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;<\/p>\n","protected":false},"template":"","class_list":["post-379292","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/379292","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\/379292\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=379292"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
