I am in APDL 23R2 and thus SHELL91 is a deprecated element type and I am unable to run an analysis on this model. Unfortunately this model has thousands of nodes and defined materials\/elements so I can&#8217;t just restart from scratch and build the file again. Is there any way to convert these SHELL91 elements into SHELL281 or a similar element type that I will be able to run an analysis on. Any thoughts are appreciated, thank you!<\/p>\n","protected":false},"template":"","class_list":["post-326287","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["48392","200"],"_bbp_author_ip":["96.7.74.191"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["129"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["326287"],"_bbp_forum_id":["27790"],"_bbp_engagement":["200","48392"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["326402"],"_bbp_last_active_id":["326402"],"_bbp_last_active_time":["2023-12-05 10:34:29"]},"test":"gackallgatech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/326287","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\/326287\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=326287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
