I tried two approaches, a full harmonic analysis and then one with mode superposition.<\/p>\n<p>In the full analysis, I used a static structural analysis to provide the pre-stress condition, however, the displacement harmonic load is not available.<\/p>\n<p>When using mode superpositon, after the static structural analysis, there&#8217;s a modal analysis, and then the harmonic analysis. The displacement harmonic load is availale, but there&#8217;s an error message saying that this type of load cannot be used when the solution method is set to Mode Superposition, and it&#8217;s not possible to change it to another solution method.<\/p>\n<p>It&#8217;s worth pointing out that in the static analysis, the surface that is subjected to harmonic displacement in the harmonic analysis, is set as a Fixed Support.<\/p>\n<p>Any help wil be appreciated.<\/p>\n<p>Cheers,<\/p>\n<p>Fabi&aacute;n&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-369972","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["184.24.96.177"],"_bbp_subscription":["350467","240"],"_btv_view_count":["530"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1717635012:313362"],"_bbp_likes_count":["1"],"_bbp_topic_id":["369972"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","350467"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["370673"],"_bbp_last_active_id":["370673"],"_bbp_last_active_time":["2024-07-05 11:08:00"]},"test":"2fa7ea0b84bb478601ff6bbecbbf86dc3b0d86aa"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/369972","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/369972\/revisions"}],"predecessor-version":[{"id":370003,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/369972\/revisions\/370003"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=369972"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
