HI there

I'm v v new to fluent...so plz help me folks!

Plz let me know which prg language and compiler (On win 7) I need to learn for writing an udf in Fluent version 6.3.26 and Ansys-Fluent 13 ..I have access to both of these versions.
I Googled for the same and I found out that its Visual C++ language and Microsoft Visual C++ compiler (on windows) that I need.
However when I checked out Ansys-Fluent 13.0 udf tuts I suspect the tuts code is in C (not in visual C++) ..
here is the CODE from the tut file on porous media:

/*******************************************************************/
/*                                                                 */
/* Position-Dependent Porous Media                                 */
/*                                                                 */
/*******************************************************************/

#include "udf.h"

DEFINE_SOURCE(xmom_source, cell, thread, dS, eqn)
{
const real c2=100.0;
real x[ND_ND];
real con, source;

C_CENTROID(x, cell, thread);
con = c2*0.5*C_R(cell, thread)*x[1];
source = - con*fabs(C_U(cell, thread))*C_U(cell, thread);
dS[eqn] = - 2.*con*fabs(C_U(cell, thread));
  
return source;
}

plz anyone who knows about this well help me out ..
I don't know much abt C and almost nothing abt visual c++

Any help is appreciated!!

There isn't much difference between C and C++ , you can start learning one of them and then you can code in the other one too, and compiler doesn't matter , you can even compile with borland C++ or RAD Studio , the important thing is to have a good and working compiled files. that's all

Best Regards
