saurabhg2014 New Member saurabh gupta Join Date: Jun 2014 Posts: 9 Rep Power: 12	As far as i know that Mixture model uses mixture rule to formulate a property of mixture from different phase properties but if i have to define any different relationship among phase material properties then which Macro (DEFINE PROPERTY ??) should i use to write UDF and where it will be hooked up ...i mean in individual phase properties or somewhere else in FLUENT. In my case mixture viscosity is a function of two primary and secondary phase viscosity but this function is not mixing law.Any help?
