Firstly I changed tire material properties(10x), used four remote points and applied mass point in the body remote point instead of the body part. I got an acceptable result, but it differed from the paper&rsquo;s result and was predictable because of the material difference.&lt;br&gt;For the next step, I added temp DOF to simulate heat generation due to friction between the Tire and runway. I add some commands to items as follows:&lt;br&gt;Tire ,Rim, and Runway parts:&lt;br&gt;et,matid,226,11&lt;br&gt;Frictional contact between Tire (contat) and Runway (Target):&lt;br&gt;keyopt,cid,1,1&lt;br&gt;rmodif,cid,18,0.1&lt;br&gt;keyopt,cid,10,2&lt;br&gt;Bonded contact between Tire and Rim:&lt;br&gt;keyopt,cid,10,2&lt;br&gt;I didn&rsquo;t encounter any error, but the temperature is ridiculously high, and I don&rsquo;t have any idea about that. Temperature increases quickly after the Tire touches the runway from 22 to above 3000 Celcius degrees. Even there are negative temperatures less than -3000. I&rsquo;m really confused. Can anyone help?&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/09\/22-09-2023-1695366463-New.png\" alt=\"New Model\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-308024","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/308024","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\/308024\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=308024"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
