Hello everybody,

I want to plot contours of a custom surface reaction rate introduced through a UDF. I know it should be done using defined memory, F_UDMI. I have tried some modifications of the udf routine, still unseccessfully. Can anybody help me on this issue? Thanks!
Below is my UDF:

#include "udf.h"
/************************************************** *********
Custom surface reaction rate UDF
************************************************** **********/
#define LP1 8.4e-5
#define KF 7.e+6
#define densi 1.19

/* Species numbers. Must match order in Fluent panel */
#define ACE 0
#define MET 1
#define NUM_SPECS 3

/* Superficial Reaction (kmol/(m2*s)) */
real ConACE = 1.;
real r1;
ConACE = densi*yi[ACE]/mw[ACE];
r1 =LP1*ConACE/(1.7+KF*ConACE);
*rr = r1;

Cpassa said how to do it: use a UDM. Unfortunately, their UDF does not use any UDM, so we don't know what they tried, and how they failed.

I suggest you do it better: add a UDM to this code, compile it, use it, and share your result (or where it went wrong). It's much easier to help if we can see where it went wrong.
"The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform" is NOT the error after compiling. It is the error after loading. To see compiler errors, look at your screen after you click "build".
