difference between Macro UDF & C programming UDF
Hi
i am new be In udf Writing , recently after reading ansys lectures about udf writing some question come in mind ! 1: what is different between Macro UDF and C programming UDF Structure , for example if i write code in C programming, should use Fluent Function Such C_R(C,t) For define density or could another type ? 2:if i use fluent function in C programming udf structure how define Fluent library to compiler ? Thank you for respond and help |
1. I don't understand the question. Fluent's density is C_R, so if you want to interact with it, use that name. I find it hard to imagine what other possibilities you are thinking about...
2. In the same way in both cases. #INCLUDE |
Hi ,
I am thankful For attention to question. if I want Write Code in C , i can define D as Density Parameter and i don't need to use C_R(c,t) function in compiler , also if i define C_R(c,t) Need to define Fluent Library in Compiler data base for Run it , Now My Question is here , if i use Fluent library and Code such functions and etc. , in Program and udf body structure , compiler never distingue that functions on the other hand if I use sample Parameter ( D = C_R ) , how define D as Density in Fluent ? may be share a sample Code For C programming UDF ? thank you |
I don't understand your problem.
If you are able to use D for density in your code, you are also able to type C_R instead. Why don't you just do that? And I don't understand what code sample you are asking for. ALL fluent UDFs are in c. Maybe you should give a code sample of what you are trying to do, that might clarify things. |
