integer, dimension(nfabor) izfppp,
integer, dimension(nfabor,nvar) icodcl,
double precision, dimension(nfabor,nvar,3) rcodcl )
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
                         -  (negative if gain) \f$w.m^{-2} \f$ or
                         -  roughness in \f$m\f$ if  icodcl=6
