BC
(required) define flag for boundary conditions
In the alias section, the BC flag attaches boundary conditions to boundary elements. Several AliasForGeometryItems might share the same boundary conditions.
Example:
Referencing the definition of the boundary conditions $BC_wall$ in the alias section applies the boundary conditions to all boundary elements with that alias.
See also: BoundaryConditions
The index of the boundary conditions can be visualized on the pointcloud with the index %ind_BC% :
# definition of boundary conditions $BC_wall$ for velocity, pressure and dynamic pressure
BC_p($BC_wall$) = (%BND_wall%)
BC_v($BC_wall$) = (%BND_wall%)
BCON($BC_wall$,%ind_p_dyn%) = (%BND_wall%)
...
