FlightGear open-source flight simulator flightgear.org

2D heat equation simulation (finite differences, 5-point stencil) implemented in sequential C++, OpenMP and CUDA, with performance benchmarks and heat-map visualizations. Up to ~70× faster on the GPU.

The GROMACS molecular simulation toolkit.

Multi-agent reinforcement learning testbed: a top-down 2D defense game where a team of agents must protect a flag from waves of enemies that get faster and more numerous over time. Fully batched PyTorch simulation on CUDA (thousands of arenas in parallel), PPO / MAPPO with MLP, GRU, LSTM and attention policies, benchmarks. The goal: cooperation that emerges from a shared reward.

Ad hoc queue simulation laboratory with 20- and 200-customer experiments, automated data generation, Google Sheets processing, and confidence interval analysis.

Pyxel Config Lab is a visual YAML configuration builder and tutorial viewer created to help people explore Pyxel simulation modes through a more intuitive and interactive interface.

Pyxel is a general detector simulation framework (https://esa.gitlab.io/pyxel). An easy-to-use framework that can simulate a variety of imaging detector effects combined on images (e.g. radiation and optical effects, noises) made by CCD or CMOS-based detectors.

Pyralysis is a Python library for radio interferometry: visibility simulation, gridding, optimization-based image reconstruction, and analysis pipelines with Dask-friendly scaling, documented APIs, and optional cluster (SLURM) workflows. GPL-3.0.

Claude Code plugin for GitLab team members: contribute to GitLab without a GDK, and reproduce self-managed GitLab on throwaway VMs that delete themselves.

Vendor-Independent, Fully Verified, Open Source VHDL Common Library

Documentation of Gaia Sky

Simulated thermocycler for demo purposes.

The project provides Python tool-chain and shell scripts for molecular simulation workflows: preparation, running and analysing molecular dynamics (MD) simulations of bio- and organic soft condensed matter.

A SOFA Framework plugin for advanced visual rendering based on the Filament rendering engine

Electromagnetic Simulation Using the FDTD Method with Python

mlafactory is an open-source discrete-event simulation framework for modeling Multi-Level Assembly (MLA) manufacturing systems.

A set of services for military scenarios in FlightGear.

New EUFS driverless simulation for Formula Student. Successor of eufs_sim

An edutainment game about running the mail, in the style of the late-'80s and early-'90s greats. Real USPS, census and labor data from 1900 on; portable C89 core for web, 68k Macintosh and more.

Python research code testing Prophet as a forecasting model. Includes random-walk and autocorrelation simulations, a hyperparameter tuning sweep, M4 hourly, weekly and daily benchmarks against naive, ETS, Theta and MSTL, and a rolling-origin evaluation on the Peyton Manning series.
