BiGSTARS.jl

Bi-Global Stability Analysis of Rotating Stratified Flows (BiGSTARS ⭐): A linear stability analysis tool for Geophysical flows with Julia. Bi-global stability analysis offers a pragmatic alternative between 1D (too idealized) and fully tri-global (often too expensive) approaches. BiGSTARS.jl gives geophysical fluid dynamicists a practical middle ground: spectral Chebyshev–Fourier discretizations, shift-and-invert eigensolvers, and ready-to-run benchmarks for rotating, stratified flows so you can resolve key instabilities without the need for massive computational resources.

Installation

Open the Julia REPL, press ] to enter package-manager mode, and run the following commands. These will add BiGSTARS and automatically instantiate all of its dependencies:

julia julia> ] (@v1.11) pkg> add BiGSTARS (@v1.11) pkg> instantiate

BiGSTARS.jl requires Julia 1.10 or newer.

Examples

Example scripts can be found in the examples/ directory. For the clearest overview, we recommend browsing them through the package’s documentation.
