This will trigger the output of the relative joint rotations in the output file JNTFORC, which can be accessed through LS-PrePost. To this end, the *CONSTRAINED_JOINT_STIFFNESS_GENERALIZED keyword will only require the definition of the fields in Card 1. The remaining cards can be left blank if no joint stiffness, stop angles, etc. are required.<\/p>\n","protected":false},"template":"","class_list":["post-165111","topic","type-topic","status-publish","hentry","topic-tag-ls-dyna","topic-tag-ls-dyna-suite","topic-tag-lsdyna","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3\/15\/2023 20:20"],"_bbp_forum_id":["27789"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["817"],"siebel_km_number":["2068080"],"product_version":[""],"km_published_date":["2022-06-25T00:00:00.000Z"],"family":["Structural Mechanics"],"application_name":["LS-DYNA Suite"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/165111","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":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/165111\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=165111"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
