Re: specific heat
Hey Man, I think you have to use UDF function. You can see many example about DEFINE_PROPERTY macros in UDF manual. If you don't have this manual please say me. Best Regards, Farid,

Re: specific heat
Yes you are right that we can define all properties by UDF. All bur not a specific heat. Bellow is an part of UDF Tutorial:
{".......UDFs cannot be used to de ne speci c heat properties; speci c heat data can be accessed only and not modi ed in FLUENT........" 4.3 Model-Dependent DEFINE Macros} So haw to deal with it? regards |
