I have already conducted some analyses using static growth option but having some problems with fatigue option.<\/p>\n<p class=\"MsoNormal\">First of all, when trying to select material for the body in the SMART Crack Growth tool, it just stays yellow (see picture), indicating the material was not assigned. Is there a specific way I should select the body or is there something I&rsquo;m missing here?<\/p>\n<p class=\"MsoNormal\">What about the load, should I be using tabular load since the pressure inside the pipe is fluctuating or how this is taken into account when using fatigue option?<\/p>\n<p class=\"MsoNormal\">Also, let&#8217;s say I would like to incorporate a medium such as hydrogen into the simulation to see how it affects the fatigue crack growth rate, is the multiphysics simulation with Ansys Fluent the right way to proceed?<\/p>\n<p class=\"MsoNormal\">Any other tips related to fatigue crack analysis are also welcome.<\/p>\n<p class=\"MsoNormal\">Thank you.<\/p>\n<p class=\"MsoNormal\">&nbsp;<\/p>\n<p class=\"MsoNormal\"><img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/10-01-2024-1704909695-SMARTfatigue.PNG\" alt=\"\" width=\"366\" height=\"681\"><\/p>\n","protected":false},"template":"","class_list":["post-344051","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["56311","490"],"_bbp_author_ip":["23.206.193.154"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1056"],"_bbp_topic_status":["answered"],"_bbp_topic_id":["344051"],"_bbp_forum_id":["27791"],"_bbp_engagement":["490","56311"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["344320"],"_bbp_last_active_id":["344320"],"_bbp_last_active_time":["2024-01-11 18:56:42"]},"test":"samuli-vilkkigmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/344051","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/344051\/revisions"}],"predecessor-version":[{"id":344374,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/344051\/revisions\/344374"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=344051"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
