Original Data for SPH and Free-Surface Flow Simulation Based on Improved Particle Shifting Technique

Raw particle data generated by Fortran code on the Visual Studio platform (source code not public as it is the core of our lab project). Simulations are computed with uniform time steps and cover three cases: numerical wave making, square droplet rotation, and droplet oscillation. Each particle file follows a consistent column schema: id, X, Y, VX, VY, density, pressure.Special datasets are included: (i) wave-probe records for numerical wave making—first column is time; subsequent columns are wave heights from probes placed every 0.25 m—plus wave-making particle data; (ii) center-of-mass pressure and total energy for the square droplet rotation; (iii) horizontal semi-major-axis evolution for droplet oscillation—first column is time; second is axis length. Data can be visualized (e.g., in MATLAB) to reproduce the figures reported in the associated article.The dataset primarily comprises results obtained with NPST (Normal Particle Shifting Technique) and IPST (Improved Particle Shifting Technique). It also includes NPST results at multiple spatial resolutions. Users can extract and compare these subsets for analyses such as convergence studies and the time-history curve of pressure at the domain center, as presented in the paper.
