<p><p>Hello, I am working on a 2D static structural in ansys workbench, I solving for a  assembly of circular ring and solid elliptical cam, refer to the attached image. I am using 2 steps for this, in 1st step = using frictionless contact with interface treatment of ” Add offset, ramped effect.” 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<\/p><p>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<\/p><table dir=”ltr” border=”1″ cellspacing=”0″ cellpadding=”0″ data-sheets-root=”1″ data-sheets-baot=”1″><colgroup><col width=”100″><col width=”100″><col width=”100″><\/colgroup><tbody><tr><td> <\/td><td>Step 1<\/td><td>Step 2<\/td><\/tr><tr><td>Frictionless<\/td><td>Alive<\/td><td>Dead<\/td><\/tr><tr><td>Bonded<\/td><td>Dead<\/td><td>Alive<\/td><\/tr><\/tbody><\/table><p>Please suggest required contact settings.<\/p><p>Images attached : 1) Inital Geometry  2) Deformation after step1  3) Deformation after step2.<\/p><p> <\/p><p>\"\" \"\" \"\"<\/p><\/p><p> <\/p><p>\"\"<p> <\/p><p> <\/p><p> <\/p><\/p><\/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":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
