Undeclared Identifier Errof UDF
 

Hi everyone,
I'm running fluent on windows xp 32bit and trying to compile a UDF with Visual Studio 9.0 (2008). I've done everything reported within this website:

-set the environmental variables for Visual Studio
-set the environmental variable for fluent
-launch fluent from the Visual C++ command window after browsing to the .cas and .dat folder

However I'm still not able to compile it correctly.
It is worth noting that the some source files compile perfectly on a Linux 64bit machine!

Done.

Does anyone have the same problem?
Thank you so much

Hello,

Could you solve this problem?

No I'm sorry

I could solve it. My problem was the UDF I was using was written in Linux and I was using it in Windows. I noticed that I needed to write my data type first. For example, for your error " 'real' : illegal use of this type as an expression", define your variable at the top of your loop before any declaration.

Hi, that's a great news, I'm still dealing with it. What do you mean exactly? Do you declare all of them even if are local variables at the top of the code?
Thanks
STefano

Remedios, could you explain on how you solved it?

I am facing similiar problem.

According to "left of '->storage' must point to struct/union" error I had the same problem. This is a part of a code, that is supposed to calculate temperature on face, but it is not a case:

begin_f_loop(f,thr_outlet)
{
real area=0.0;

real NV_VEC(farea); /* defines vector "farea"*/
F_AREA(farea,f,t); /* computes area of each face */
area = NV_MAG(farea);

area_sum = area_sum + area;
sum_area_temp = sum_area_temp + area * F_T(f,thr_outlet); /* additions subsequent temperatures on faces */
}
end_f_loop(f,thr_outlet)
}

Those two thread names should be the same. I left default one after pasting from another source. After changing "f" on "thr_outlet" in "F_AREA" problem was solved. Hope this helped at least a bit.
