Hi. Simple question.

I'm trying to interpret my UDFs, and to make things simple I'll just copy Example 2 from:
http://www.afs.enea.it/project/neptu...udf/node46.htm.

It looks like this. What do I need to do to implement it in my model?

#include "udf.h"

DEFINE_PROPERTY(mass_wtd_k,c,t)
{
real sum = 0.; int i;
Material *sp;
real ktc;
Property *prop;
mixture_species_loop(THREAD_MATERIAL(t),sp,i)
{
prop = (MATERIAL_PROPERTY(sp));
ktc = generic_property(c,t,prop,PROP_ktc,C_T(c,t));
sum += C_YI(c,t,i)*ktc;
}
return sum;
}

When I try to interpret it like I usually do I get the error "structure reference not implemented" on the mixture_species_loop line.
What have I missed to be able to interpret Example 2?
As it's the example code, there is something obvious I'm missing.

If I instead try to use the compiler I just get a bunch of error messages about it not being compiled for parallel use and that the system can't find the file specified.

Help!

I've code above with no errors

Thanks for the reply!
The clue was in the error message. I run fluent in x64 parallel mode, and to be able to compile just about anything I have to open fluent via the Visual Studios x64 command prompt.

Otherwise the compiler can't find the library files.
