I am using 2 steps for this, in 1st step = using frictionless contact with interface treatment of &#8221; Add offset, ramped effect.&#8221; to tackle the intial interface and expecting that circular ring will take shape of elliptical cam. In step 2 = using bonded contact, cause I want, there should not be any relative motion between two parts after assembly&lt;\/p&gt;&lt;p&gt;Problem facing : I succesfuly completed step 1 but after step1 completion there is slight gap between two edges approx 40-50 microns and due to that in step 2 I am not able to create bonded contact, solver showing convergence error and end up on inital stage. So can I create bonded\/rough contact between edges with slight gap in between&lt;\/p&gt;&lt;table dir=&#8221;ltr&#8221; border=&#8221;1&#8243; cellspacing=&#8221;0&#8243; cellpadding=&#8221;0&#8243; data-sheets-root=&#8221;1&#8243; data-sheets-baot=&#8221;1&#8243;&gt;&lt;colgroup&gt;&lt;col width=&#8221;100&#8243;&gt;&lt;col width=&#8221;100&#8243;&gt;&lt;col width=&#8221;100&#8243;&gt;&lt;\/colgroup&gt;&lt;tbody&gt;&lt;tr&gt;&lt;td&gt;&nbsp;&lt;\/td&gt;&lt;td&gt;Step 1&lt;\/td&gt;&lt;td&gt;Step 2&lt;\/td&gt;&lt;\/tr&gt;&lt;tr&gt;&lt;td&gt;Frictionless&lt;\/td&gt;&lt;td&gt;Alive&lt;\/td&gt;&lt;td&gt;Dead&lt;\/td&gt;&lt;\/tr&gt;&lt;tr&gt;&lt;td&gt;Bonded&lt;\/td&gt;&lt;td&gt;Dead&lt;\/td&gt;&lt;td&gt;Alive&lt;\/td&gt;&lt;\/tr&gt;&lt;\/tbody&gt;&lt;\/table&gt;&lt;p&gt;Please suggest required contact settings.&lt;\/p&gt;&lt;p&gt;Images attached : 1) Inital Geometry&nbsp; 2) Deformation after step1&nbsp; 3) Deformation after step2.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/04-09-2024-1725447491-Initial geometry.png\" alt=\"\" width=\"435\" height=\"371\" \/> <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/04-09-2024-1725447506-after step 1.png\" alt=\"\" width=\"562\" height=\"362\" \/> <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/04-09-2024-1725447534-after step 2.png\" alt=\"\" width=\"619\" height=\"360\" \/>&lt;\/p&gt;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/04-09-2024-1725449857-bonded contact setting.png\" alt=\"\" \/>&lt;p&gt; &lt;\/p&gt;&lt;p&gt; &lt;\/p&gt;&lt;p&gt; &lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-381516","topic","type-topic","status-answered","hentry","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-bondedcontactfailure-1","topic-tag-contact","topic-tag-convergence"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["344162","13640"],"_bbp_author_ip":["103.21.126.81"],"_btv_view_count":["1791"],"_bbp_topic_status":["answered"],"_edit_last":["344162"],"_bbp_revision_log":["a:1:{i:381526;a:2:{s:6:\"author\";i:344162;s:6:\"reason\";s:0:\"\";}}"],"_bbp_topic_id":["381516"],"_bbp_forum_id":["27791"],"_bbp_engagement":["13640","344162"],"_bbp_voice_count":["2"],"_bbp_last_reply_id":["381728"],"_bbp_last_active_id":["381728"],"_bbp_last_active_time":["2024-09-06 11:58:27"]},"test":"dbb96e10fe71988b37eb4bda74811cf8ad0e148c"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/381516","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\/381516\/revisions"}],"predecessor-version":[{"id":381526,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/381516\/revisions\/381526"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=381516"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
