Traveling Wave Database
This is a database of equilibria (EQ) and traveling waves (TW) (also known as relative equilibria) for Kolmogorov flow with the parameters commonly used in the literature. Specifically nu=1/40 and a vorticity forcing of -4cos(4y). The boundary conditions are periodic and the domain is [0,2pi]^2.
Currently providing 534 EQ and 6,134 TW.
I saved these to independent h5 files with example MATLAB and Python scripts to access the data.
EQ.h5 - EQ dataset
TW.h5 - TW dataset
example.m - Load solutions in MATLAB and verify they solve the TW condition.
example.py- Load solutions in Python
TW_objective.m - Clarify any uncertainty in conventions by evaluating the TW condition.
I did a sweep to check for duplicates, but no promises that there are absolutely none. These solutions appear in no particular order. While all solutions are converged below 1e-12 in the TW condition, this does not mean the solution itself is that accurate. I have not done a convergence study in grid resolution or beyond double precision.
Contact Matthew Golden (mgolden@lanl.gov) with questions or comments. My plan is to update this as I find more solutions.
