If the two cracks are far apart. crack growth can be established. However, if the two cracks are close to each other(about 5~10 mm). I will encounter this error problem(as shown in the picture).&nbsp;&lt;\/p&gt;&lt;p&gt;There is no problem in different crack depths under static conditions, but it becomes unfeasible when switching to fatigue conditions.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/23-09-2024-1727101226-mceclip0.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp; &nbsp; &nbsp;&lt;\/p&gt;&lt;p&gt;Here are some parameter settings&lt;\/p&gt;&lt;p&gt;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Crack1&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Crack2&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SMART crack growth&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/23-09-2024-1727101361-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;Boundary conditions&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/23-09-2024-1727101457-mceclip2.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-383756","topic","type-topic","status-publish","hentry","topic-tag-fatigue-crack-growth","topic-tag-fracture-mechanics","topic-tag-semi-elliptical-crack","topic-tag-smart-crack-growth"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["437713","157520"],"_bbp_author_ip":["140.115.65.120"],"_btv_view_count":["1101"],"_bbp_topic_status":["unanswered"],"_edit_last":["437713"],"_bbp_revision_log":["a:1:{i:383765;a:2:{s:6:\"author\";i:437713;s:6:\"reason\";s:11:\"SMART crack\";}}"],"_bbp_notification_enabled":["437713","437713","437713","437713","437713","437713","437713","437713","437713"],"_bbp_topic_id":["383756"],"_bbp_forum_id":["27791"],"_bbp_engagement":["157520","437713"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["387779"],"_bbp_last_active_id":["387779"],"_bbp_last_active_time":["2024-10-02 08:41:10"]},"test":"liuguanhong32gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/383756","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\/383756\/revisions"}],"predecessor-version":[{"id":383765,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/383756\/revisions\/383765"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=383756"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
