In the solver wizard after importing the the reference and signal files, when I go to the variables tab, both of them are real vector data types instead of XY data. That creates an error in the next step when creating the calculation for the error_norm variable. I get the same result in 2024 R2. I&#8217;ve set the Token Max = 2 which highlights the second column of data, but in the &#8220;instant visualization&#8221; it only shows the time data linearly increasing, not the displacement data.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Instead of following the tutorial instructions to import as plain text, if I import with auto-parameterization, it creates a response as a XY data type. And the expected plot shows in instant visualization. Could somebody provide clarification on how to use the import plain text and get XY data?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-424305","topic","type-topic","status-publish","hentry","topic-tag-optislang"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["275024"],"_bbp_topic_id":["424305"],"_bbp_subscription":["21912","284998"],"_bbp_author_ip":["18.10.77.35"],"_bbp_last_reply_id":["424407"],"_bbp_last_active_id":["424407"],"_bbp_last_active_time":["2025-03-05 11:47:19"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["21912","284998"],"_btv_view_count":["248"],"_bbp_topic_status":["unanswered"]},"test":"seijiengmit-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/424305","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\/424305\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=424305"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
