problem with boundary

#1 Unread post by duckweed »

Hi,
i don't know how to set the boundary conditions. which boundary condition can share with other conditions? and who can tell me the means of every boundary conditions,such as what does mean the EAST_VOLCONS and EAST_FSRADIATION.i only konw the means of closed boundary.
Thanks!

OPTIONS to impose mass conservation at the open boundary: **
** **
** EAST_VOLCONS use if Eastern edge mass conservation enforcement **
** WEST_VOLCONS use if Western edge mass conservation enforcement **
** NORTH_VOLCONS use if Northern edge mass conservation enforcement **
** SOUTH_VOLCONS use if Southern edge mass conservation enforcement **
** **
** OPTIONS for periodic boundary conditions: **
** **
** EW_PERIODIC use if East-West periodic boundaries **
** NS_PERIODIC use if North-South periodic boundaries **
** **
** OPTIONS for closed boundary conditions: **
** **
** EASTERN_WALL use if Eastern edge, closed wall condition **
** WESTERN_WALL use if Western edge, closed wall condition **
** NORTHERN_WALL use if Northern edge, closed wall condition **
** SOUTHERN_WALL use if Southern edge, closed wall condition **
** **
** Additional OPTION for radiation open boundary conditions: **
** **
** RADIATION_2D use if tangential phase speed in radiation conditions **
** **
** Eastern edge open boundary condtions OPTIONS: **
** **
** EAST_FSCHAPMAN use if free-surface Chapman condition **
** EAST_FSGRADIENT use if free-surface gradient condition **
** EAST_FSRADIATION use if free-surface radiation condition **
** EAST_FSNUDGING use if free-surface passive/active nudging term **
** EAST_FSCLAMPED use if free-surface clamped condition **
** EAST_M2FLATHER use if 2D momentum Flather condition **
** EAST_M2GRADIENT use if 2D momentum gradient condition **
** EAST_M2RADIATION use if 2D momentum radiation condition **
** EAST_M2REDUCED use if 2D momentum reduced-physics **
** EAST_M2NUDGING use if 2D momentum passive/active nudging term **
** EAST_M2CLAMPED use if 2D momentum clamped condition **
** EAST_M3GRADIENT use if 3D momentum gradient condition **
** EAST_M3RADIATION use if 3D momentum radiation condition **
** EAST_M3NUDGING use if 3D momentum passive/active nudging term **
** EAST_M3CLAMPED use if 3D momentum clamped condition **
** EAST_KGRADIENT use if TKE fields gradient condition **
** EAST_KRADIATION use if TKE fields radiation condition **
** EAST_TGRADIENT use if tracers gradient condition **
** EAST_TRADIATION use if tracers radiation condition **
** EAST_TNUDGING use if tracers passive/active nudging term **
** EAST_TCLAMPED use if tracers clamped condition **
