◆ cs_boundary_conditions_set_coeffs()

void cs_boundary_conditions_set_coeffs ( int  nvar,
int  iterns,
int  isvhb,
int  itrale,
int  italim,
int  itrfin,
int  ineefl,

)

Translation of the boundary conditions given by the user in a form that fits to the solver.

The values at a boundary face $ \fib $ stored in the face center $ \centf $ of the variable $ P $ and its diffusive flux $ Q $ are written as:

\[ P_{\face} = A_P^g + B_P^g P_{\centi} \]

and

\[ Q_{\face} = A_P^f + B_P^f P_{\centi} \]

where $ P_\centi $ is the value of the variable $ P $ at the neighboring cell.

Warning
  • If we consider an increment of a variable, the boundary conditions read:

    \[ \delta P_{\face} = B_P^g \delta P_{\centi} \]

    and

    \[ \delta Q_{\face} = -B_P^f \delta P_{\centi} \]

  • For a vector field such as the velocity $ \vect{u} $ the boundary conditions may read:

    \[ \vect{u}_{\face} = \vect{A}_u^g + \tens{B}_u^g \vect{u}_{\centi} \]

    and

    \[ \vect{Q}_{\face} = \vect{A}_u^f + \tens{B}_u^f \vect{u}_{\centi} \]

    where $ \tens{B}_u^g $ and $ \tens{B}_u^f $ are 3x3 tensor matrix which coupled velocity components next to a boundary.

Please refer to the boundary conditions section of the theory guide for more informations, as well as the condli section.
