StructIQ is an open-source, AI-assisted structural engineering platform that combines traditional FEM with real-time AI support to optimize, simulate, and innovate building designs. It features digital twin capabilities, global building code compliance, predictive hazard analysis, advanced visualization, and an education/training mode. Fully modular, future-proof, and licensed under AGPL 3.0+. https://roxanneardary.com/structiq/

Pulse is a factory simulator developed in C. The project aims to reproduce, in a simple and modular way, the behavior of an industrial installation

The GROMACS molecular simulation toolkit.

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.

The pytest-fusesoc plugin allows to use pytest to discover and run simulation targets defined in FuseSoC *.core files. Furthermore, test capabilities can be greatly increased with existing pytest plugins, pytest built-in features like fixtures, test parametrization @pytest.mark.parametrize, tests reporting and more.

NeuroML-based neural simulator

Open Arsenal provides open, self-hosted software specifications designed for deployment across private and public networks. Built for portability, interoperability, and transparency, each specification gives organizations the freedom to implement and customize solutions without vendor lock-in while remaining free to use under the AGPL-3.0+ license with required attribution. Specification Branding Licenses available upon request. https://roxanneardary.com/open-source-projects/

A set of services for military scenarios in FlightGear.

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.

A simulator for our future-planned kernel, Nitrocid Kernel!

OpenLeverage Lab is an open-source financial simulation engine that models margin borrowing, portfolio risk, and repayment dynamics under real-world uncertainty. It combines deterministic financial calculations with probabilistic stress testing, including Monte Carlo simulations and extreme market scenarios, to forecast leverage outcomes before capital is committed. Designed with a fully modular architecture, it enables transparent, reproducible, and extensible risk analysis for leveraged financial decision-making. https://roxanneardary.com/openleverage-lab/
