Jul 1, 2025July 2025: PlasmaControl/DESC delivered key features, improved API reliability, and expanded documentation to accelerate adoption and value realization. Key features include Iota profile support in the ASCII writer with warning suppression; API updates adding contract equilibrium and Fourier-Zernike profile; deprecation warnings to steer users toward current APIs; module load statement and naming clarity refinements; extensive docs and examples covering net enclosed flux, eq.Psi, contract equilibrium, VMEC input file assumptions, and install/docs; new examples for adding_objectives and related tutorials (GenericObjective, ObjectiveFromUser). Major bugs fixed include kinetic profiles and ASCII output issues with a recommended shift to HDF5 output; improved from_field error handling; and a small typo fix. Impact: clearer API surface, reduced onboarding friction, increased stability, and richer learning materials enabling faster model development. Technologies/skills demonstrated: Python, API design and versioning, documentation and examples, deprecation strategy, error handling, and VMEC input-file context.

May 1, 2025May 2025 (PlasmaControl/DESC) focused on delivering robust features, safer defaults, and improved modeling capabilities across coil visualization, optimization workflows, and field parameterization. The work emphasizes business value through more reliable simulations, clearer user guidance, and greater modeling flexibility. Key features delivered: - Plot coils visualization enhancements: introduced a check_intersection flag to coil plotting to optionally skip intersection checks; applied related code formatting improvements. (commits include: add flag to not check intersection when plotting coils; black formatting) - Equilibrium optimization defaults: changed default constraints to ForceBalance and required explicit objective/constraints with user warnings; updated tests and test tweaks to reflect the new API. - SGD optimization: improved logging by printing metrics before termination checks and ensured proper failure signaling when max iterations are reached. - Flexible FourierXY and spline field parameterization: added curve parameter 's' and enabled a source grid specification for Field discretization, increasing modeling flexibility. - VMEC spline profile derivative fix: corrected derivative access for spline profiles when writing VMEC input to prevent generation errors. Major bugs fixed: - VMEC spline profile derivative access issues during VMEC input generation (commit: 44024a1a3e7e0d8e238a057b9c656216dfeed3e9). - Tests adjusted and fixed for equilibrium optimization defaults and mandatory args (several commits in the eq.optimize series: c0cebc02..., 6aa9698..., 5d1ec342..., f6fe990..., c738fa0a...). Overall impact and accomplishments: - Reduced risk of user errors with safer defaults and explicit API requirements, enabling clearer workflows for optimization and plotting. - Increased modeling flexibility (source grids and curve parameterization) enabling more accurate representation of experimental configurations. - Improved observability through better logging and robust plotting diagnostics, contributing to faster iteration and debugging. Technologies/skills demonstrated: - Python-based numerical optimization, plotting, and I/O workflows. - Test-driven development and test maintenance for evolving APIs. - Code quality improvements including formatting (Black) and API clarity. - Data integrity and dimensionality handling in multi-dimensional arrays and field discretization.

Dec 1, 2024December 2024 in PlasmaControl/DESC: Delivered NFP attribute support and compatibility checks to improve physical fidelity, fixed associated attribute validation bug, and enhanced documentation and changelog accuracy. Reliability improvements included a reverse-mode rotation matrix fix, expanded test coverage with failing tests resolved, and fitter API improvements to stabilize VMEC geometry fitting. Engineering modernization moved lambdify to set_potentials, shifted to a jax-differentiable potential after SymPy integration, and updated dependencies. Overall impact: higher physics accuracy, more robust testing and maintenance, and clearer, up-to-date documentation for users and contributors.
