Hi,

I am confused about switiching on boundary conditions options in cppdefs.h. I am trying to set up a simulation as close as possible to a ROMS_RUTGERS simulations. This is a realistic coastal model having wind, tides, rivers, bulk forcing, etc.

In the ROMS_RUTGERS, I am using the following boundary conditions in the input text file (roms.in which is similar to croco.in). The boundary conditions are shown in this image:

ROMS_RUTGERS boundary conditions

What are the correct equivalent options for croco? My case has North boundary closed.

Currently I have the following cpp option in my croco cppdefs.h file:

Am I using the correct OBC options? Because I am getting a blow up after few time steps. Reducing the dt and ndtfast is just delaying the blowup. I am attaching my full cppdefs.h here.

I am using boundary forcing file and not climatology file. Here is the metadat of my bry forcing file: bry.txt

Any suggestion and help will be much appreciated.

Thanks!

Thanks! It seems to be working. And my guess is the M2/M3SPECIFIED is equivalent to the 'CLAMPED' condition in roms_rutgers, just for future reference?

It would be great to get confirmation what exactly "SPECIFIED" means for M2/M3/T.
