Computational data and code for Separating field scale, voltage partition and channel survival in floating-conductor double-gap discharges

This dataset contains computational outputs and implementations associated with the study of field scale, voltage partition and channel survival in floating-conductor double-gap discharges. It includes 66 axisymmetric electrostatic case outputs and numerical-control comparisons; stored summary/comparison tables for 2,818 sequential-event conditions; fixed interpolation coefficients and archived common random samples; matched field-scale/partition and deadline/survival analyses; and source data and exports for eleven figures. These are simulated and deterministically derived data, not experimental observations. Data-only Python routines use deposited tables without a new field or event calculation. Full field regeneration requires separately licensed COMSOL Multiphysics and MATLAB. Software installers and third-party literature are not included. Data, configurations, figures and documentation are licensed under CC BY 4.0; the 36 MATLAB/Python source files are licensed under MIT. The exact file-level division is specified in LICENSE_SCOPE.csv. Code copyright: 2026 Wenli Zhu. Version 1.0.2 is a maintenance release of version 1.0.1 (10.5281/zenodo.22741358). It standardizes the copyright-holder name as Wenli Zhu, translates two console messages to English, and updates distribution metadata and file identities. Scientific inputs, archived results, fixed samples, acceptance thresholds, operational safety restrictions and all figure exports are unchanged. No scientific or plotting routine was executed for this release. Earlier public versions remain available and unchanged. Cite the version-specific DOI assigned to this release for these exact files.
