BoundaryConditions
definition of physical boundary conditions for boundary elements
Boundary conditions are an essential ingredient for the simulation model. They are defined and then attached to boundary elements in the alias section. They must be provided according to the solver choice.
General Syntax
Boundary conditions for all relevant variables can be defined by:
Here,
BC_p and
BC_v are specialized keywords for pressure and velocity, respectively, and
BCON is a more general keyword to define boundary conditions for arbitrary variables.
These boundary conditions are then related to boundary elements in the alias section (see
AliasForGeometryItems) with the
BC-flag:
begin_alias{}
"BoundaryName" = " ...MOVE$MOVEindex$ ... BC$BCindex$ ... SMOOTH_LENGTH$Hindex$ ... "
