57  * \brief Boundary conditions for smooth walls (icodcl = 5).
58  *
59  * The wall functions may change the value of the diffusive flux.
60 
61  * The values at a boundary face \f$ \fib \f$ stored in the face center
62  * \f$ \centf \f$ of the variable \f$ P \f$ and its diffusive flux \f$ Q \f$
63  * are written as:
64  * \f[
65  * P_{\face} = A_P^g + B_P^g P_{\centi}
66  * \f]
67  * and
68  * \f[
69  * Q_{\face} = A_P^f + B_P^f P_{\centi}
70  * \f]
71  * where \f$ P_\centi \f$ is the value of the variable \f$ P \f$ at the
72  * neighboring cell.
73 
74  * Warning:
75 
76  * - For a vector field such as the velocity \f$ \vect{u} \f$ the boundary
77  * conditions may read:
78  * \f[
79  * \vect{u}_{\face} = \vect{A}_u^g + \tens{B}_u^g \vect{u}_{\centi}
80  * \f]
81  * and
82  * \f[
83  * \vect{Q}_{\face} = \vect{A}_u^f + \tens{B}_u^f \vect{u}_{\centi}
84  * \f]
85  * where \f$ \tens{B}_u^g \f$ and \f$ \tens{B}_u^f \f$ are 3x3 tensor matrix
86  * which coupled velocity components next to a boundary.

90  * section of the theory guide for more informations, as well as the
