Dear colleagues!
Here is a UDF which use:

#include "udf.h"
#include "mem.h"

Domain *domain = Get_Domain(1);
int count, massflow_zone;
real At, A[ ND_ND ], cx0[ND_ND];
cell_t c0, c1;
Thread *t, *ct0, *ct1;
face_t f;

massflow_zone = 1; // interior BC
t = Lookup_Thread(domain, massflow_zone);
begin_f_loop(f, t)
F_AREA(A, f, t);
At = NV_MAG(A);
c0 = F_C0(f, t);
ct0 = F_C0_THREAD(f, t);
C_CENTROID(cx0, c0, ct0);
Message("C_U(c0, t0): %f \n", C_W(c0, ct0));
Message("C_DUDX(c0, t0): %f \n", C_DUDX(c0, ct0));

end_f_loop(f, t);

After several iteration I executed this UDF and I got first message and on the second one I got segmentation fault. Any idea why?

Best regards!
