Where can I find the AB3-AM4 code?

Dear all,

I am running and modifying the Soliton test case, trying to use a barotropic simulation to study the dynamics of the discretized AB3-AM4 algorithm.
I am trying to find the Fortran code of the barotropic dynamical core in the Croco files, but I haven’t found them yet. More precisely, I am looking for the code implementation of the integration of the barotropic free surface, equations (3.49) and (3.50) of the Shchepetkin and McWilliams (2005) study. ( Zeta(m+1) = Zeta(m) +deltaT * div[Ubar(m+1/2)] )

I found the files that set the initial conditions and grid (ana_initial.F and ana_grid.F) in the /croco-v1.3/OCEAN/ folder. However, I haven’t found the file where the barotropic variables are integrated.

Does anyone know the folder and file where this algorithm is located?

Thanks.

I found the file. For anyone else looking for the same code, it’s located in /OCEAN/step2d.F.

I’ll leave this question up in case it helps others with the same inquiry, but I’ll leave it to the moderator to decide whether to remove it.
