Dear CFD giants

Can someone please help me understand why does this happen

udf code
cr = F_C0(f,r_thread);
printf("Face vs Cell Stress qties at Outlet\n");
ctr=0;
begin_f_loop(f,t)
{ if(ctr==30){
F_CENTROID(FCI,f,r_thread);
printf("F-Loop\n");
printf("Xcoor Ycoor %f %f\n",FCI[0],FCI[1]);
printf("TKE %f\n",F_K(f,r_thread));
printf("Diss %f\n",F_D(f,r_thread));
printf("RUU %f\n",C_RUU(cr,r_thread));
printf("RVV %f\n",C_RVV(cr,r_thread));
printf("RWW %f\n",C_RWW(cr,r_thread));
printf("RUV %f\n",C_RUV(cr,r_thread));
printf("RVW %f\n",C_RVW(cr,r_thread));
printf("RUW %f\n",C_RUW(cr,r_thread));}
ctr++;
}
end_f_loop(f,t)
ctr=0;
begin_c_loop(cr,t)
{ if(ctr==30){
C_CENTROID(FCI,cr,r_thread);
printf("C-Loop\n");
printf("Xcoor Ycoor %f %f\n",FCI[0],FCI[1]);
printf("TKE %f\n",C_K(cr,r_thread));
printf("Diss %f\n",C_D(cr,r_thread));
printf("RUU %f\n",C_RUU(cr,r_thread));
printf("RVV %f\n",C_RVV(cr,r_thread));
printf("RWW %f\n",C_RWW(cr,r_thread));
printf("RUV %f\n",C_RUV(cr,r_thread));
printf("RVW %f\n",C_RVW(cr,r_thread));
printf("RUW %f\n",C_RUW(cr,r_thread));}
ctr++;
}
end_c_loop(cr,t)

I cant understand how the values of face and cell values are so different.
My domain is a 2-D rectangular domain

Any help would be appreciated
