DESC and VMEC Inputs and Outputs for 3D Stellarator Equilibrium Comparisons

Input and output files from the DESC and VMEC 3D equilibrium codes used for comparisons in a research paper. The dataset includes files for computing plasma equilibria and plotting scripts for figures, as of the arXiv version from March 31, 2023. It was created by Dario Panici of Princeton University.

Use Cases

• Benchmarking the accuracy of 3D equilibrium codes based on plasma energy and MHD force balance metrics described in the paper.
• Comparing computational performance between DESC and VMEC algorithms for solving plasma equilibria.
• Reproducing figures from the paper 'The DESC Stellarator Code Suite Part I' using the provided plotting scripts.
• Analyzing the accuracy of equilibrium solutions near the magnetic axis, a specific finding highlighted in the description.

Strengths

• Includes data from two distinct 3D equilibrium codes (DESC and VMEC) for direct comparison.
• Associated plotting scripts facilitate figure reproduction from the specified paper version.
• Dataset was updated on May 5, 2023 for better readability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date for the underlying data is unknown; freshness unverified.
