It is an element variable. It is an array.&lt;\/p&gt;&lt;p&gt;EPST from your note is a local variable. It is not an array. It is a scalar and has a single value. See the picture below.&lt;\/p&gt;&lt;p&gt;User Subroutine &#8220;SOLVE_STR_USER_1&#8221; is called for every element automatically by Autodyn. EPST is the Effective Plastic Strain for the current element, i.e., EPST = EPS(current element #).&lt;\/p&gt;&lt;p&gt;EPST is used to interpolated plastic strain from the input of material hardenning curve (Yield Stress vs Plastic Strain) to obtain the Yield Stress for the current element.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/11\/08-11-2023-1699451500-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-315786","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/315786","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\/315786\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=315786"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
