Reducing Normal stiffness factor may help reducing the as it allows for some penetration, but you have to balance it with the need for accuracy in your simulation.&lt;br&gt;There are general tips to deal with stress singularities, you can add fillets to replace sharp edges, use the stress of nearby elements to approximate the stress at singularity regions. And if you are not interested in stress distribution in the thickness direction of the walls of steel frame, you can use shell element formulation. So, you can use finer and good quality mesh.&lt;\/p&gt;&lt;p&gt;Please refer to this free Ansys Innovation course to learn more about how to deal with such stress singularities and best practices: https:\/\/innovationspace.ansys.com\/product\/numerically-accurate-results\/&lt;br&gt;&lt;br&gt;Join structures Community feed: https:\/\/innovationspace.ansys.com\/community\/groups\/?structures-community\/&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397354","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello,As your pipes have sharp edges at the contact, stress concentration is expected.
