The model is a stack of thin-film layers with different thicknesses and material properties. I ran a thermal analysis on Thermal&ndash;Electric tool and imported those results into Static Structural to study thermal-expansion mismatch effects.&lt;br&gt;However, I&rsquo;m getting a warning: &ldquo;The maximum contact stiffness is too big.&rdquo; and also the result I saw is not realistic. I tried adjusting the normal stiffness control from Programmable to Factor in specific contacts and tested different values, but the issue still persists.&lt;br&gt;Could anyone help me on this?&lt;br&gt;&lt;br&gt;Thanks<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/09\/12-09-2025-1757675108-Screenshot 2025-09-12 104248.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-441352","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["441352"],"_bbp_subscription":["594031","423981"],"_bbp_author_ip":["143.248.72.130"],"_bbp_last_reply_id":["441763"],"_bbp_last_active_id":["441763"],"_bbp_last_active_time":["2025-09-19 09:13:11"],"_bbp_reply_count":["2"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["594031","423981"],"_btv_view_count":["2490"],"_bbp_topic_status":["unanswered"]},"test":"tinsaegbehagakaist-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/441352","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/441352\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=441352"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
