As I mentioned before the &#8220;Coupled Field Transient&#8221; analysis type seems reasonable to solve this problem or did I missunderstood this completly?<\/p>\n<p>And is it better to implement the heat caused by the friction between the two pieces as a simple heat flow as a function of time and temperature, or over the contact itself?<\/p>\n<p>Maybe someone can help me with this problem or give me some advices how to do it and if the suggestions I made are even correct?<\/p>\n<p>I am thankful for everything that helps!<\/p>\n<p>&nbsp;<\/p>\n<p>Greetings, Dominic<\/p>\n","protected":false},"template":"","class_list":["post-290047","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello!I already got some experience with Ansys Workbench but I am now facing some troubles with my current Simulation.
