PROFILE
Eirik Endeve
Endevee contributed to the endeve/thornado repository by developing a tallying system for Eulerian energy and momentum, integrating it with the two-moment framework and off-grid flux tallying to improve simulation fidelity and measurement accuracy. Using Fortran and high-performance computing techniques, they refined simulation initialization logic for better startup stability and convergence. Endevee also implemented cylindrical Riemann problem support in the Euler solver, introducing symbolic constants for maintainability and expanding geometry options. Additionally, they improved repository hygiene by removing binary artifacts from version control, ensuring maintainable and reproducible workflows. Their work demonstrated depth in scientific computing, code integration, and numerical simulation.

Jul 1, 2025July 2025: Delivered Cylindrical Riemann Problem support in the Euler solver for endeve/thornado, including cylindrical initialization and a new ApplicationDriver option. Refactored to use a symbolic Gamma_IDEAL constant for the adiabatic index, improving maintainability. Adjusted cylindrical simulations with new defaults for grid resolution, domain boundaries, and end time. No major bugs recorded this month; the work expands geometry support and enhances configurability and maintainability, enabling broader physics simulations and faster iteration.

Dec 1, 2024December 2024 performance summary for endeve/thornado. Focused on delivering physics-measurement capabilities and stabilizing startup conditions to improve simulation fidelity and reliability. The new Tallying System tracks Eulerian energy and momentum across the simulation pipeline, integrated with the existing two-moment framework and off-grid flux tallying, with driver-level changes to initialize and compute tallies at multiple stages. Initialization refined by directly assigning iPM_J and iPM_H1 in InitializationModule.F90, improving initial-condition accuracy and convergence. No major bugs reported this month; emphasis on feature delivery, code quality, and traceability. Business value realized includes more accurate energy/momentum accounting, improved startup stability, and clearer integration points for tallies with the simulation core, enabling more reliable production runs and downstream research. Technologies/skills demonstrated include Fortran-era modernization, cross-module integration, tally-design, driver-level changes, and disciplined version-control practices.
