The top part is loaded and constrained by body-ground springs. The lower part will use the displacement results of the top part at the interface as loading, and be constrained to the ground. Based on these results, I desire to update the springs&#039; stiffness, and then iterate the process.<\/p>\n<p>My issue is that the current model is using all RAM, and that the model needs refinement in certain areas, which will require more memory. I am familiar with this principle for modal analysis (super elements\/Craig-Bampton method), but not in relation to structural analysis. <\/p>\n<p>If this is possible through parametrization, please give me some hints of how to succeed, as I am currently out of ideas, since I am using solid elements.<\/p>\n<p>Thanks in advance.<\/p>\n<p>KR Chris.<\/p>\n","protected":false},"template":"","class_list":["post-168677","topic","type-topic","status-closed","hentry","topic-tag-static-structural","topic-tag-structural","topic-tag-substructuring-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["1831"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["168677"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","183504"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["212379"],"_bbp_last_active_id":["212379"],"_bbp_last_active_time":["2022-04-22 10:07:11"]},"test":"chrishart"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168677","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168677\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=168677"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
