BCON
general setting of boundary conditions
Set boundary conditions for any variable (see
__Indices__ ) for which a partial differential equation (PDE) has to be solved.
The general syntax is
This is especially important in the framework of
CODI. For all variables used in a
CODI-environment, this boundary condition
feature is important and completes the setup of the PDE.
Example:
However, this is a general function. The convenience functions BC_... are shortcuts to
BCON:
BC_v($BND$) ->
BCON($BND$,%ind_v(1)%)
BC_p($BND$) ->
BCON($BND$,%ind_p%)
BC_T($BND$) ->
BCON($BND$,%ind_T%)
BC_k($BND$) ->
BCON($BND$,%ind_k%)
BC_eps($BND$) ->
BCON($BND$,%ind_eps%)
BC_S($BND$) ->
BCON($BND$,%ind_Sxx%)
