GeFi Particle Simulation Data for Collisionless Magnetic Reconnection

1.8 GB of particle simulation data for collisionless magnetic reconnection under low plasma beta and large guide field conditions. The dataset, authored by Zhifang Guo and last updated in April 2026, contains physical parameters in 2D and 3D grids for different ion-to-electron mass ratios and simulation times. Files are provided in .dat and .nc formats.

Use Cases

• Benchmarking and validating magnetohydrodynamic (MHD) or particle-in-cell (PIC) simulation codes based on the described physical parameters.
• Analyzing the effects of ion-to-electron mass ratio on reconnection dynamics based on the provided mass ratio cases.
• Studying the evolution of electromagnetic fields and particle distributions in 2D and 3D based on the listed field and velocity components.
• Investigating the role of guide field strength in collisionless reconnection based on the dataset's stated conditions.

Strengths

• Dataset size of 1.8 GB indicates a substantial volume of simulation output.
• Includes data for four distinct ion-to-electron mass ratios (100, 400, 900, 1836) enabling comparative studies.
• Provides both 2D (256x512 grid) and 3D (256x512x64 grid) data for spatial analysis.
• Simulation outputs are captured at multiple time steps (e.g., t=20, 30, 40 Ωi⁻¹) for temporal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
