Boundary conditions for smooth walls (icodcl = 5).
The wall functions may change the value of the diffusive flux.
The values at a border face
stored in the face center
of the variable
and its diffusive flux
are written as:
and
where
is the value of the variable
at the neighbooring cell.
Warning:
the boundary conditions may read:
and
are 3x3 tensor matrix which coupled veclocity components next to a boundary. | subroutine clptur | ( | integer | nscal, |
