 * \brief Boundary conditions for smooth walls (icodcl = 5).
 *
 * The wall functions may change the value of the diffusive flux.
 
 * The values at a boundary face \f$ \fib \f$ stored in the face center
 * \f$ \centf \f$ of the variable \f$ P \f$ and its diffusive flux \f$ Q \f$
 * are written as:
 * \f[
 * P_{\face} = A_P^g + B_P^g P_{\centi}
 * \f]
 * and
 * \f[
 * Q_{\face} = A_P^f + B_P^f P_{\centi}
 * \f]
 * where \f$ P_\centi \f$ is the value of the variable \f$ P \f$ at the
 * neighboring cell.
 
 * Warning:
 
 * - For a vector field such as the velocity \f$ \vect{u} \f$ the boundary
 *   conditions may read:
 *   \f[
 *   \vect{u}_{\face} = \vect{A}_u^g + \tens{B}_u^g \vect{u}_{\centi}
 *   \f]
 *   and
 *   \f[
 *   \vect{Q}_{\face} = \vect{A}_u^f + \tens{B}_u^f \vect{u}_{\centi}
 *   \f]
 *   where \f$ \tens{B}_u^g \f$ and \f$ \tens{B}_u^f \f$ are 3x3 tensor matrix
 *   which coupled velocity components next to a boundary.

 * <a href="../../theory.pdf#wallboundary"><b>wall boundary conditions</b></a>
 * section of the theory guide for more informations, as well as the
