zone number for the boundary face for the specific physic module
[in,out]
icodcl
face boundary condition code:
1 Dirichlet
2 Radiative outlet
3 Neumann
4 sliding and
5 smooth wall and
6 rough wall and
9 free inlet/outlet (input mass flux blocked to 0)
13 Dirichlet for the advection operator and Neumann for the diffusion operator
[in,out]
rcodcl
boundary conditions value on edge faces rcodcl(1) = value of the Dirichlet rcodcl(2) = value of the extern exchange coef. (infinit if no exchange) rcodcl(3) = value of the flux density (negative if gain) or the rugosity high if icodcl=6 for velocity for pressure for scalar
