If you have a complex solution then the results file will have 2 sets of results for each natural freuqency &#8211; the real part and imaginary part. You can use the SET command to look at either one.&nbsp; So for example you can use the below to get the UX value at node 5 for real part of mode 1 and imaginary part of mode 1. Once you have the real and imaginary values you can calculate phase angle or amplitude.&lt;\/p&gt;&lt;p&gt;\/post1&lt;\/p&gt;&lt;p&gt;set,1,1&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;! load real part of mode 1 solution&lt;\/p&gt;&lt;p&gt;real5=ux(5)&lt;\/p&gt;&lt;p&gt;set,1,1,,1&nbsp; ! load imaginary part of solution&lt;\/p&gt;&lt;p&gt;imag5=ux(5)&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-301899","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/301899","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/301899\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=301899"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
