PROFILE
Eirik Endeve
Endevee contributed to the endeve/thornado repository by developing core simulation features and improving code maintainability. Over four months, they built a tallying system for Eulerian energy and momentum, integrating it with the two-moment framework to enhance simulation fidelity. They refined initialization logic in Fortran, directly assigning key variables to improve startup accuracy. Endevee also implemented cylindrical Riemann problem support in the Euler solver, expanding geometry options and maintainability by introducing symbolic constants. Additionally, they established macOS build automation using Makefile, enabling native builds and smoother onboarding. Their work demonstrated depth in Fortran programming, numerical simulation, and cross-platform build engineering.

Jan 1, 2026January 2026 — Endeve/thornado: Built macOS build support by adding a dedicated Makefile with macOS-specific compiler settings and library inclusions, enabling reliable native builds on macOS. This reduces onboarding time for macOS contributors and strengthens cross-platform compatibility. No major bug fixes were completed this month. Key technologies demonstrated include Makefile-based build automation, cross-platform configuration, and library linking on macOS; impact on business value: faster contributor onboarding, broader developer coverage, and more robust release workflows.

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.
