I don&#8217;t know how this happens (I have difficulty in understanding how the UDF works.).&lt;br&gt;&lt;span class=&#8221;fontstyle0&#8243;&gt;but I didn&#8217;t find the magnitude of gradient, although the code has done the calculation. C_UDMI(c,t,0) = NV_MAG(C_UDSI_G(c,t,0));&lt;\/span&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;it seems the forum didn&#8217;t send email to remind me that I get reply anymore. I don&#8217;t know why this stops.&lt;\/p&gt;&lt;p&gt;thank you again.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/07-01-2025-1736268593-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/07-01-2025-1736268533-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-403962","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/403962","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\/403962\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=403962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
