Supplementary Data: "sangkuriang: an Idealized Korteweg-de Vries solver with pseudo-spectral methods"

This repository contains NetCDF data files and 3D animated visualizations (GIF) from four benchmark test cases of the sangkuriang idealized KdV solver.

Test Cases:
- Case 1: Single soliton propagation (baseline validation)
- Case 2: Two equal solitons (phase shift dynamics)
- Case 3: Soliton collision (overtaking interaction)
- Case 4: Three-soliton system (complex multi-body dynamics)

Contents:
- NetCDF4 files with complete spatiotemporal solution data, conserved quantities (mass, momentum, energy), and simulation metadata
- 3D surface animations showing wave evolution with conservation tracking
