Boundary condition along ... (Mixing)

DESCRIPTION

Computing famillies of trajectories requires to specify some parameters along the boundaries of the domain which are specific to mixing tasks and cannot be found from Navier-Stokes boundary conditions.  This is done in this menu  (those items do not affect the flow field).
 In particular,  if one wishes that particles leaving the domain on one side be reinjected on another boundary,  one needs to specify them as Entry/Exit sections for the mixing task.   OPTIONS

 Upper level menu
0
 Non-penetrable boundary
Use this entry for a wall,  a plane of symmetry, a slip wall or when you know that the material particle will never penetrate the wall.
1
 Inflow
For  entry sections which are not periodic.
2
 Outflow
For  exit sections which are not periodic.
3 Entry boundary (in spatially periodic flow)
Periodic flows must be specified as couples of entry/exit boundaries.  The program will ask you for the "target".
4 Exit boundary (in spatially periodic flow)
The boundary set specified as the "target" of an inlet of periodic flow will be automatically assigned this attribute.
5 Parameters for spatially periodic boundaries
The transformation matrix/vector,  component by component.
