My problem is that I&#8217;m trying to design a CFM resembling a gripper in static structural using TPU95A as the material. So far, I&#8217;ve tried activating large deflection, setting initial and minimum substeps to 100, and maximum substeps to 1000. I used Keyopt(6)==1 and Keyopt(2)==1. Additionally, I sized my mesh to 1.6mm, which I think is decent. I tried all these things because TPU95A is an elastomer; nevertheless, deformation results are still linear instead of nonlinear. What can I try now? Has anyone designed a CFM in ANSYS before?<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-size: 12pt\">PD: Sorry for my bad english.<\/span><\/p>\n","protected":false},"template":"","class_list":["post-357798","topic","type-topic","status-closed","hentry","topic-tag-Forcecalculation-1","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-error","topic-tag-mechanical","topic-tag-workbench"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["341554","240"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["252"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1710906466:292302"],"_bbp_topic_id":["357798"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","341554"],"_bbp_voice_count":["2"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["358422"],"_bbp_last_active_id":["358422"],"_bbp_last_active_time":["2024-03-22 03:30:51"]},"test":"l19030399morelia-tecnm-mx"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/357798","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\/357798\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=357798"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
