FjordSim.jl

A framework for ocean simulations built on top of Oceananigans and ClimaOcean.

One of the main contributions to ClimaOcean is providing a streamlined way to set up simulations. A FjordSim simulation is organized around three core components:

1. Bathymetry file Contains the domain coordinates (longitude, latitude, depth) along with the bathymetric data.

2. Forcing file Includes information about sinks and sources (e.g., rivers), boundary conditions, and custom forcings. It can also be used to load initial conditions.

3. Atmospheric data Currently relies on JRA55 from ClimaOcean.

Preparation scripts for the Oslofjord are available in the following repository: https://github.com/NIVANorge/oslofjord-sim

Installation (from GitHub)

1. Clone the git repository git clone https://github.com/AquaBadgerForge/FjordSim.jl.git.
2. Move to the downloaded folder cd FjordSim.jl.
3. Run Julia REPL and activate the FjordSim environment julia --project.
4. Enter the Pkg REPL by pressing ] from Julia REPL.
5. Type instantiate to 'resolve' a Manifest.toml from a Project.toml to install and precompile dependency packages.

Run an example Oslofjord simulation

1. Download the grid, forcing, atmospheric forcing.
2. In FjordSim.jl/app/oslofjord.jl it is possible to specify the location of the input data files. By default, the files should be in $HOME/FjordSim_data/oslofjord/ and $HOME/FjordSim_data/JRA55/. Also, it is possible to specify the results folder destination. By default, the result will go to $HOME/FjordSim_results/oslofjord/.
3. Run julia --project app/oslofjord.jl. This will generate a netcdf result file.
