<p dir=”auto”>I’m working with ANSYS 2022R1 and encountering an issue when exporting a System Coupling setup for a coupled Fluent-Mechanical analysis. Despite ensuring that all components of the analysis (Fluent, Mechanical, and System Coupling systems) are fully updated and the coupling interfaces\/data transfers are defined in the System Coupling Setup cell, the export process only generates two .scp files (fluent.scp and Mechanical.scp) instead of the expected .sci file for a full setup.<\/p><p dir=”auto”>I’ve followed the standard export procedure:<\/p><\/p>\n

    \n
  1. Completed the setup for both participant systems (Fluent and Mechanical).<\/li>\n
  2. Defined the coupling interfaces and data transfers in the System Coupling system.<\/li>\n
  3. Right-clicked the System Coupling Setup cell and exported setup to a new working directory.<\/li>\n
  4. Checked the export log, which indicates a full setup export was attempted, but no .sci file is present—only the .scp files and SyC\/Settings.h5.<\/li>\n<\/ol>\n

    <p dir=”auto”>I need the .sci file to run the simulation on a cluster using syscserver, as the separate .scp files don’t seem to include the coupling definition. Can anyone advise:<\/p><ul dir=”auto”><\/p>\n

  5. Why the .sci file isn’t being exported despite a full setup?<\/li>\n
  6. Any specific settings or steps I might have missed in Workbench to ensure the .sci file is generated?<\/li>\n
  7. Alternative ways to combine the .scp files or use them directly with syscserver if the .sci export can’t be resolved?<\/li>\n<\/ul>\n","protected":false},"template":"","class_list":["post-438118","topic","type-topic","status-answered","hentry","topic-tag-mechanicalworkbench-1","topic-tag-2-way-coupled-fsi","topic-tag-2-way-fsi","topic-tag-2022-r1-1","topic-tag-coupled-system","topic-tag-export-file","topic-tag-fluent","topic-tag-fluent2022r1-1","topic-tag-systemcoupling"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["438118"],"_bbp_subscription":["578579","15845"],"_bbp_author_ip":["130.64.3.61"],"_bbp_last_reply_id":["438152"],"_bbp_last_active_id":["438152"],"_bbp_last_active_time":["2025-07-30 11:19:08"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["578579","15845"],"_btv_view_count":["151"],"_bbp_topic_status":["answered"]},"test":"kaeden-frestontufts-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/438118","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\/438118\/revisions"}],"predecessor-version":[{"id":438578,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/438118\/revisions\/438578"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=438118"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
