A small thermal contact conductance can also be used to represent a thin layer of material with a different conductivity, such as a gasket.<\/p>\n<p class=\"p\">For large values of thermal contact conductance, the resulting temperature discontinuity tends to vanish and perfect thermal contact is approached. With a zero value, however, the solver assumes that no heat is transferred across the contacting surfaces.<\/p>\n<p id=\"r_structural_contactgroup_tools__note_tfm_ffy_22c\" class=\"note note note_note\"><strong><span class=\"note__title\">Note:<\/span> <\/strong>While the application can solve with a value of 0, which specifies no electric transfer between the faces, a project with a 0 value for electric conductance is invalid when exported to the <span class=\"keyword\">Workbench <\/span>application. You must then replace zero conductance with some small value.<\/p>\n<hr \/>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-197904\" src=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-300x240.png\" alt=\"\" width=\"300\" height=\"240\" srcset=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-300x240.png 300w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-768x615.png 768w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-24x19.png 24w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-36x29.png 36w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile-48x38.png 48w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/01\/Thermal_Conductance_AIS_Tile.png 996w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-197903","topic","type-topic","status-publish","hentry","topic-tag-conductance","topic-tag-contact","topic-tag-contact-heat-transfer","topic-tag-heat-transfer","topic-tag-thermal-conductance","topic-tag-thermal-load","filter-by-application-ansys-discovery","filter-by-application-discovery-explore","filter-by-application-discovery-geometry","filter-by-application-discovery-refine"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_edit_lock":["1775034261:3452"],"_edit_last":["3452"],"_aioseo_title":[null],"_aioseo_description":[null],"_aioseo_keywords":["a:0:{}"],"_aioseo_og_title":[null],"_aioseo_og_description":[null],"_aioseo_og_article_section":[""],"_aioseo_og_article_tags":["a:0:{}"],"_aioseo_twitter_title":[null],"_aioseo_twitter_description":[null],"filter_by_optics_product":["Lumerical"],"_filter_by_optics_product":["field_64fb192ba3121"],"application_name":[""],"_application_name":["field_64a80903c8e15"],"family":[""],"_family":["field_64a809229a857"],"siebel_km_number":[""],"_siebel_km_number":["field_63ecbffce60db"],"salesforce_km_number":[""],"_salesforce_km_number":["field_63ecc018e60dc"],"km_published_date":[""],"_km_published_date":["field_64c77704499dd"],"product_version":[""],"_product_version":["field_64c776cb4fd2e"],"_bbp_forum_id":["159537"],"_bbp_topic_id":["197903"],"_bbp_author_ip":["192.104.24.227"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["197905"],"_bbp_last_active_time":["2026-01-13 07:35:21"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["0"],"_btv_view_count":["86"]},"test":"watchlearnansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/197903","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":2,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/197903\/revisions"}],"predecessor-version":[{"id":197906,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/197903\/revisions\/197906"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=197903"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
