I fed the mechanical stress-strain data for each of the four sections the &#8220;engineering data&#8221; section. The structure is made in Spaceclaim as 4 different frustums sketched drawn along the same axis and then, &#8220;aligned&#8221; using the arrangement tool.&nbsp;&lt;\/p&gt;&lt;p&gt;When I try to map the deformation in this structure (defined a fixed support and deformation direction), these are errors I am getting:&lt;\/p&gt;<\/p>\n<ol>\n<li>An error occurred when the post processor attempted to load a specific result. Please review all messages, or<\/li>\n<li>the reference convergence value may be less than the threshold, you can overwrite the minimum reference value by specifying it under nonlinear controls of analysis settings.<\/li>\n<\/ol>\n<p>&lt;p&gt;I tried adjusting the tolerance value and decreasing the minimum reference (for displacement convergence) in the Analysis Setting (image below) but nothing worked. Any help will be helpful:)&lt;\/p&gt;&lt;p&gt;&nbsp;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/08\/28-08-2024-1724879087-mceclip0.png\" width=\"531\" height=\"250\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/08\/28-08-2024-1724879354-mceclip1.png\" width=\"333\" height=\"89\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-380953","topic","type-topic","status-publish","hentry","topic-tag-Modal_Analysis-1","topic-tag-material-nonlinearity-1","topic-tag-non-convergence"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["342748","240"],"_bbp_author_ip":["152.7.224.49"],"_btv_view_count":["859"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["380953"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","342748"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["381284"],"_bbp_last_active_id":["381284"],"_bbp_last_active_time":["2024-09-01 21:02:14"]},"test":"apragyancsu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/380953","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\/380953\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=380953"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
