Implementation of Ogata's (2005) method for Hankel transforms.

homebrew

:beer: The missing package manager for OS X.

icyantics.jl

Simulations of sea ice dynamics in the Oceananigans ecosystem

jupyter-notebook-slides

linear-stability-calculators

Code will solve the linear stability problems for a variety of physicsl models: quasi-geostrophy, shallow water and quasi-hydrostatic. The code is in either Julia or Python.

mytest

Testing how to create a repo

oceananigans.jl

🌊 Fast and friendly fluid dynamics on CPUs and GPUs

pseudopy

PseudoPy computes and visualizes the pseudospectrum of a matrix

pyfftw

A pythonic python wrapper around FFTW

pyqg

2-layer QG model

pysw

Python code to solve the Rotating Shallow Water Model

qg_1l

Compute the stability of 1-Layer QG model with topography. Assume the flow is periodic in x and a channel in y. Converted from matlab to petsc4py/slepc4py

qg_1l_ts

Time stepping. Uses Crank-Nicholson

qg_basin

Converted a code from matlab to petsc4py/slepc4py. Includes a petscKron function.

qg_vortex

qg_vortex_ts

Based off of qg_vortex_stab_ts.m by Francis J. Poulin in collaboration with Claire Menesguen

qgmodel

Python code that solves nonlinear QG equations

rsw_1l

sw_1L_channel_np2ps_stab.py Creates A using numpy/scipy then moves rows to petsc4py matrix Could use eig, eigs, or slepc sw_1L_channel_ps_fixed.py A (petsc) built with separate parts, using the other numpy matrices (Dy, dH, etc.) sw_1L_channel_np_stab2.py and sw_1L_channel_n_stab.py see v5.2 above basically, just use numpy only. 2 ways of making A (2 is better/faster) sw_1L_channel_ps_newguess.py petsc only – guess changes to be the previous one just calculated. Still need an initial guess.vvv

rsw_rect

Based off of rsw_rect_reduced.m by Ben Storer

shallowwaters.jl
