whats the difference between cell 2 and cell3 ? it's not clear from your sketch

sketch is wrong for cell1 as boundary can't cross center of cell in Fluent

hi, thanks for your attention,
- fluent save date in cell center and dash line for cell1 is imaginary boundary(for more description),
- cell3 position and properties is different with cell2.
numerical domain is full of cells and I draw 3 cells for sample.
thanks.

hi, thanks for attention,
this problem has be solved,
please see below code if interest for you,

begin_f_loop_int(f0,tf0)
if PRINCIPAL_FACE_P(f0,tf0)
{
tc1 = THREAD_T0(tf0);
c1 = F_C0(f0,tf0);
c_face_loop(c1,tc1,n)
{
f1_temporary = C_FACE(c1,tc1,n);
tf1_temporary = C_FACE_THREAD(c1,tc1,n);
if (F_C1(f1_temporary,tf1_temporary) == c1)
{
tf1 = C_FACE_THREAD(c1,tc1,n);
f1 = C_FACE(c1,tc1,n);
}
}
tc2 = THREAD_T0(tf1);
c2 = F_C0(f1,tf1);
gfcp = (C_CP(c1,tc1) + C_CP(c2,tc2)) / 2;
khc = (C_K_L(c1,tc1) + C_K_L(c2,tc2)) / 2;
tj1 = C_T(c1,tc1);
tj2 = C_T(c2,tc2);
F_CENTROID(pos0,f0,tf0);
C_CENTROID(pos1,c1,tc1);
C_CENTROID(pos2,c2,tc2);
dy1 = pos0[1] - pos1[1];
dy2 = pos1[1] - pos2[1];
alp = dy2 / dy1;
.
.
.
other actions in udf codes for problem ...
.
.
.
}
end_f_loop_int(f0,tf0)

number 0 for cell 1,
number 1 for cell 2,
