The code performs spectral simulations using Dedalus for the rotating formulation of the Genarlized Navier-Stokes equations on a sphere (Eqs. 2.3 here).

Dedalus (install using conda)

Activate the conda dedalus environment and go to the standalone directory:

conda activate dedalus
cd standalone

Specify the run parameters and output folder in standalone/runningSimulation.py.

Run the script:

mpiexec -n <ncores> python3 runningSimulation.py

For an example of plotting and making a video from the saved data:

python3 plot_output.py
