Analytical test LBC(isFsur)==Cla ask for *.nc file

[pelijas]

Hi

I'm new in ROMS and I'm trying to set-up an analytical case.
I wish to simulate a gravity current falling down a slope, that is orientated East (shallow) to West(deep),
and I want to Clamp all my LBC on the east side. So my LBC are:

I want to run it without any tidal force and I defined in the canyon.h
ana_initial, ana_tobc, ana_m3obc, ana_m2obc.


LBC(isFsur) == Clo Per Cla Per ! free-surface
LBC(isUbar) == Clo Per Cla Per ! 2D U-momentum
LBC(isVbar) == Clo Per Cla Per ! 2D V-momentum
LBC(isUvel) == Clo Per Cla Per ! 3D U-momentum
LBC(isVvel) == Clo Per Cla Per ! 3D V-momentum
LBC(isMtke) == Clo Per Cla Per ! mixing TKE

LBC(isTvar) == Clo Per Cla Per\ ! temperature
Clo Per Cla Per ! salinity


When I tried to run it with the ana_m2obc Roms is looking for a BRYNAME file *.nc.

Is not possible to run with LBC(isFsur) == Cla analytically? In this case, why?
Because if I change it to any other option (Fla,Cha,Gra,Rad....) it runs.

Any help would be apreciated!
Thanks in advance.

You also need to #define ANA_FSOBC for providing the value you are clamping to. Give that a try.

Thanks a lot Kate, it works!!!!
