If you are talking about a shadow face, they take the same ID.

I talke about an elementary face (f) for a grid. to solve the heat equation with a term source (surface condensation phenomenon ), one using a finite volume methods, it is necessary for me to know the neighbor face for each face f.

See UDF manual pp. 5-6 to 5-9.

F_C0(f,tf) and F_C1(f,tf) give you the adjacent cells' indices.

THREAD_T0(tf) and THREAD_T1(tf) give you the ajacent threads.

Good luck!

What are you talking about?

If you have a grid:

|-2-|-5-| 1 3 6 |-4-|-7-|

What is the "neighbour face" of face 3?

Sorry, this board has a few issues with white space - I should have previewed it. If you have a quad grid, of two cells. The face between them is face 3. The faces on one cell are 1, 2, 3, and 4 and on the other are 3, 5, 6 and 7.

If you have a grid:

| - 2 - | - 5 - |

1.......3.......6

| - 4 - | - 7 - |

What is the "neighbour face" of face 3?
