Default help with macros F_ID and C_ID

Hello everyone

In my problem statement I am required to address specific cell and face element on a boundary. Please note I am addressing this issue for a parallel solver.

I found that in mem.h the Fluent.Inc has provided macros F_ID and C_ID to obtain the global face and cell id. I hope, in parallel solver the face id we obtain using these macros are equal to their index (face_t f) defined in serial solver. However, while using this macros in a very simple UDF, Fluent always give following error, "Segmentation Vioation"

The sample UDF is below

#include "udf.h"



#if !RP_HOST

face_t f;

Thread *t;

Domain *d;








Message0("\nThe face id is %d \n", F_ID(f,t));




#endif /* #if RP_NODE */

#endif /* #if !RP_HOST */


Look forward to hear yours expert opinion on this topic.

Regards Jack
