Boundary conditions for smooth walls (icodcl = 5).

file cs_boundary_conditions_set_coeffs_turb.c

The wall functions may change the value of the diffusive flux.

The values at a boundary face $\fib$ stored in the face center $\centf$ of the variable and its diffusive flux are written as:

$P_{\face} = A_P^g + B_P^g P_{\centi}$

and

$Q_{\face} = A_P^f + B_P^f P_{\centi}$

where $P_\centi$ is the value of the variable at the neighboring cell.

Warning:

For a vector field such as the velocity $\vect{u}$ the boundary conditions may read:
$\vect{u}_{\face} = \vect{A}_u^g + \tens{B}_u^g \vect{u}_{\centi}$
and
$\vect{Q}_{\face} = \vect{A}_u^f + \tens{B}_u^f \vect{u}_{\centi}$
where $\tens{B}_u^g$ and $\tens{B}_u^f$ are 3x3 tensor matrix which coupled velocity components next to a boundary.

Please refer to the wall boundary conditions section of the theory guide for more informations, as well as the clptur section.
