So udf is giving that message. nIf you are uisng UDM, please make sure that you you assign UDM before compiling UDF. nnRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn
