Hi,
Recently, I wanted to use CROCO to simulate some NBQ processes, but I have some confusion regarding the LBC settings in CROCO. In ROMS, my settings were as follows:
Lateral Boundary Conditions: NLM
Variable Grid West Edge South Edge East Edge North Edge
zeta 1 Chapman Imp Chapman Imp Chapman Imp Chapman Imp
ubar 1 Flather Clamped Flather Flather
vbar 1 Flather Clamped Flather Flather
u 1 Radiation Clamped Radiation Radiation
v 1 Radiation Clamped Radiation Radiation
temp 1 Radiation Clamped Radiation Radiation
salt 1 Radiation Clamped Radiation Radiation
dye_01 1 Radiation Clamped Radiation Radiation
tke 1 Gradient Gradient Gradient Gradient
In CROCO, the settings are as follows.
undef TIDES
define OBC_EAST
define OBC_WEST
define OBC_NORTH
define OBC_SOUTH
undef OBC_VOLCONS /for no tidal simulation/
define OBC_M2FLATHER /radiative OBC for barotropic velocities/
define OBC_M3ORLANSKI
define OBC_TORLANSKI
My question is how to set different open boundary conditions for different boundaries(i.e. the south edge)?
