The simulation runs fine but I found out after reviewing the results that Fluent sends the force calculated from the STATIC pressure component only to the system coupling. This is very bad in my case because I have a compressible fluid (air ideal gas) which is flowing at high speeds (mach 2 in some spots) so the force due to dynamic pressure needs to be accounted for as well. The only information I found on this is from this post about a year ago where it seems like ANSYS developers knew this is a problem (\/forum\/forums\/topic\/fsi-problem-importing-pressures-from-fluent-to-static-structural\/) . Has anyone found a work around to this yet???? Is there any way to change how FLuent is calculating this force?&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-363366","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["87093","805"],"_bbp_author_ip":["96.7.218.215"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["293"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1713805517:296456"],"_bbp_topic_id":["363366"],"_bbp_forum_id":["27792"],"_bbp_engagement":["805","87093"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["366044"],"_bbp_last_active_id":["366044"],"_bbp_last_active_time":["2024-05-08 09:20:06"]},"test":"njf5255psu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/363366","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\/363366\/revisions"}],"predecessor-version":[{"id":363589,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/363366\/revisions\/363589"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=363366"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
