The bottom box is fully constrained using a rigid body definition, and the top platen is only allowed to move in the loading direction.&lt;\/p&gt;&lt;p data-start=&#8221;550&#8243; data-end=&#8221;859&#8243;&gt;My goal is to obtain the force exerted by the top platen on the Miura plate so that I can plot a force versus displacement curve. However, when I attempt to extract this using the &ldquo;reaction force&rdquo; or &ldquo;external force&rdquo; options in Workbench, I receive an error message stating: &lt;em data-start=&#8221;825&#8243; data-end=&#8221;857&#8243;&gt;&ldquo;Extraction of result failed.&rdquo;<\/em>&lt;\/p&gt;&lt;p data-start=&#8221;861&#8243; data-end=&#8221;991&#8243;&gt;I would appreciate any guidance on how to correctly obtain the force output for this type of displacement-controlled simulation.&lt;\/p&gt;&lt;p data-start=&#8221;993&#8243; data-end=&#8221;1014&#8243; data-is-last-node=&#8221;&#8221; data-is-only-node=&#8221;&#8221;&gt;Thank you in advance!&lt;\/p&gt;&lt;p&gt;&nbsp;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/04\/13-04-2026-1776076589-Screenshot 2026-04-13 132945.png\" alt=\"\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/04\/13-04-2026-1776076611-Screenshot 2026-04-13 133010.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-456350","topic","type-topic","status-publish","hentry","topic-tag-Forcecalculation-1","topic-tag-force-displacement","topic-tag-lsdyna"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["456350"],"_bbp_subscription":["675237","58821"],"_bbp_author_ip":["130.233.138.200"],"_bbp_last_reply_id":["456449"],"_bbp_last_active_id":["456449"],"_bbp_last_active_time":["2026-04-14 15:42:45"],"_bbp_reply_count":["4"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["675237","58821"],"_btv_view_count":["125"],"_bbp_topic_status":["unanswered"]},"test":"akshay-kalgutkaraalto-fi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/456350","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\/456350\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=456350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
