Sep 1, 2025September 2025 (2025-09): WarpX delivered key physics enhancements and usability improvements that strengthen simulation stability, physical realism, and end-user workflows. Sub-orbit time stepping for the implicit solver was implemented to reduce particle convergence failures, with updates to particle attributes and deposition routines to preserve accuracy across time steps. Bremsstrahlung photon generation collisions were added using physics models based on Seltzer & Berger, expanding the radiative processes available in WarpX and supported by updated docs and tests. A Python interface example plus an API refactor for input handling was introduced to simplify direct Python parameterization (bypassing PICMI), including a 3D plasma lens test case and Python input file. These changes enhance scientific fidelity, broaden user workflows, and are underpinned by comprehensive tests and documentation to ensure reliability and adoption.

Apr 1, 2025April 2025 saw focused reliability and accuracy improvements for EZoni/WarpX. Key work included memory-safety hardening in VandB deposition routines (1D/2D) to prevent bad memory access, with a new CI-tested 2D implicit VandB deposition case added to strengthen coverage. In parallel, CODATA 2022 constants were updated and the CI/test workflow was modernized by upgrading the build environment to Ubuntu 24.04 and refactoring tests/inputs to use scipy.constants and internal constants for consistency. These efforts improve simulation stability, numerical accuracy, and development feedback loops, supporting more trustworthy production runs and faster iteration cycles.
