I am trying to avoid getting local mode shapes in the vertical direction in which I have no interest. I am in the process of simplifying my building model by removing some weaker walls which results in some floors getting to &quot;bendy&quot; as loosing some support. I know some programs have that options, where You can define in which DOF the mass is acting (X, Y, Z, RX, RY, RZ), but I don`t seem to find this option in ANSYS.<\/p>\n<p><\/p>\n<\/p>\n<p>Thanks for Your answers<\/p>\n","protected":false},"template":"","class_list":["post-158615","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2596"],"_bbp_likes_count":["0"],"_bbp_subscription":["231790"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["158615"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","184550"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["179152"],"_bbp_last_active_id":["179152"],"_bbp_last_active_time":["2021-05-21 06:19:18"]},"test":"biokill"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/158615","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\/158615\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=158615"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
