It works here in testing, at least back to version 2022R2. C_MU_T is the turbulent viscosity for k-e, k-w and transition SST models. Have you hooked your UDF function into the meaterial properties for the UDS diffusivity? You could add the line&lt;\/p&gt;&lt;p&gt;Message(&#8220;c_mu_t = %e \\n&#8221;, C_MU_T(c,t));&lt;\/p&gt;&lt;p&gt;to your UDF and run for 1 iteration to see what is happening. Only macros documented in the Customization manual are supported.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-313100","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/313100","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\/313100\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=313100"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
