Hi there,
When I am using C_YI_G(cellg,threadg,0) (line 10)
in rest of DEFINE_EXECUTE_AT_END Macro: (which written to get gradient of concentration of water(0))
1) real delphig[ND_ND]={0.,0.};
2) d = Get_Domain(1);
3) tg = Lookup_Thread(d,5);
4) begin_f_loop(fg,tg)
5) {
6) cellg=F_C0(fg,tg);
7) threadg = THREAD_T0(tg);
8) F_YIg= F_YI(fg,tg,0);
9) C_YIg= C_YI(cellg,threadg,0);
10) NV_VS(delphig, =, C_YI_G(cellg,threadg,0), /, 1.0); //i dont know
if it is correct way of vector assigning
11) }
12)end_f_loop(fg,tg)

FLUENT abnormally is exited. the error in log is Received signal SIGSEGV

I try to solve my problem by Adjust Macro and UDSI_G but the same result i get.

Even, i set (rpsetvar 'species/save-gradients? #t) but the error can't remove.

Any idea of you surely helps me to get gradient of the concentration in a boundary

thank you in advance
