Supplementary data for: Klahn, M., Zhai, Y. & Fuhrman (2024) Heavy tails and probability density functions to any nonlinear order for the surface elevation in irregular seas. J. Fluid Mech. 985, A35.

This data set contains supplementary data for Klahn, Fuhrman & Zhai (2024).

File PFL.zip contains a Matlab structural array (PFL) with the simulated surface elevations (five realizations) from the fully nonlinear Pseudospectral-Fourier-Legendre (PFL) model (Klahn et al. 2021) at time t = 50T_p, where T_p is the peak wave period.

Once unzipped, data can be loaded into Matlab and viewed using e.g.:

>> load PFL.mat; [X,Y] = meshgrid(PFL.x,PFL.y); pcolor(X,Y,PFL.eta{1}); shading interp; colormap jet; colorbar

For further details, please see the README file.
