Border_Domain_Boundary_Conditions

This data setup allows the user to define the boundary conditions at the ends of the domain like symmetric planes or periodical conditions.

The Full data set of the namelist

 &Border_Domain_Boundary_Conditions 
  West_BC_Name  = "None" , 
  East_BC_Name  = "None" , 
  Back_BC_Name  = "Periodic" , 
  Front_BC_Name = "Periodic" , 
  North_BC_Name = "None" , 
  South_BC_Name = "None" /
  • The name of each end is given by its orientation with respect to the adjoined fluid cells, namely “WEST”, “EAST”, “BACK”, “FRONT”, “SOUTH” and “NORTH” for the directions “i-1”, “i+1”, “j-1”, “j+1”, “k-1” and “k+1” respectively.
  • By default the domain is enclosed. The boundary conditions defined by default at the ends of the domain are walls. These wall boundary conditions are set with the namelists "Heat_Wall_Boundary_Condition_Setup", "Velocity_Wall_Boundary_Condition_Setup" or "Species_Wall_Boundary_Condition_Setup"
  • Walls can be partially or totally removed either by inlet/outlet boundary conditions (see the namelists Inlet_Boundary_Condition, Outlet_Boundary_Condition ) or the boundary conditions showed here (symmetric plans or periodical conditions).
  • Variables set to “None” can be removed (default value).
