Re: Dye boundary doesn't work when using passive tracer

The RadNud boundary condition nudges the boundary value towards the specified value. This will only affect the interior values when the radiative scheme diagnoses inflow. So: Have you set a nudging time scale for dye at the southern boundary? Have you waited long enough to see an effect in the ...

Re: Dye boundary doesn't work when using passive tracer

i have not added a dye BC in a while, but I think you are missing a few things. - i assume you have something like NPT = 2 ! Number of inactive passive tracers - i think you need to add: ! Each tracer variable requires [1:4,1:NAT+NPT,Ngrids] values. Otherwise, ... LBC(isTvar) == Clo Per Gra Per ...

Dye boundary doesn't work when using passive tracer

Hello,everyone! I meet a problem when I add the passive tracer. This is my step to add passive tracer: 1. define Passive tracer in .h file. #define T_PASSIVE #define AGE_MEAN #define ANA_BPFLUX /* analytical bottom passive tracers fluxes */ #define ANA_SPFLUX 2.add dye_01 and dye_age_01 to initial ...
