Hi

I'm facing a problem with including some packages in a UDF. I'm looking for a general way or description of how the packages are found and how to include them in the UDF.

All UDF start with:
#include "udf.h"

However, if I want to include other packages such as iostream, I've tried:
#include "iostream"
#include <iostream>
#include "iostream.h"
#include <iostream.h>
, but everytime I try to compile the UDF within Fluent, I get the following errors:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\xtgmath.h(214) : warning C4602: #pragma pop_macro : 'new' no previous #pragma push_macro for this identifier
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(23) : error C2061: syntax error : identifier 'abs'
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(23) : error C2059: syntax error : ';'
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(23) : error C2061: syntax error : identifier 'acos'
...
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(53) : error C2061: syntax error : identifier 'erf'
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(53) : error C2061: syntax error : identifier 'erfc'
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\cmath(53) : fatal error C1003: error count exceeds 100; stopping compilation

It seems like a problem with cmath. I'm using Fluent v. 17.1.

Best regards Anders

Hi. No, I haven't found a solution, so I'm not using that package, though I can't remember, why I wanted it. :P

I think you need to include the library "math.h" be cause he doesnt understand the "abs" which for absolute value and "acos" for inverse cosine and "erf" or erfc are some functions of that library. if I dont make a mistake.
