Parameters
[in]itypfbboundary face types
[in]izfpppzone number for the boundary face for the specific physic module
[in,out]icodclface boundary condition code:
  • 1 Dirichlet
  • 2 Radiative outlet
  • 3 Neumann
  • 4 sliding and $ \vect{u} \cdot \vect{n} = 0 $
  • 5 smooth wall and $ \vect{u} \cdot \vect{n} = 0 $
  • 6 rough wall and $ \vect{u} \cdot \vect{n} = 0 $
  • 9 free inlet/outlet (input mass flux blocked to 0)
  • 13 Dirichlet for the advection operator and Neumann for the diffusion operator
[in,out]rcodclvalue of the boundary conditions to edge faces 
                         boundary condition values:
                          - rcodcl(1) value of the dirichlet
                          - rcodcl(2) value of the exterior exchange
                          -  coefficient (infinite if no exchange)
                          -  rcodcl(3) value flux density

                          -  roughness in \form#498 if  icodcl=6
                           -# for velocity:
$(\mu+\mu_T)\gradv \vect{u}$
  1. for pressure: $ \Delta \grad P \cdot \vect{n} $
  2. for scalar: $ C_p \left ( K + \dfrac{K_T}{\sigma_T} \right) \grad T \cdot \vect{n} $
