OpenMolcas is a quantum chemistry software package.

The key feature of OpenMolcas is the multiconfigurational approach to the electronic structure.

PhysicsMesh Platform is a law-driven simulation system that computes physical reality through invariant physics laws rather than approximation or animation heuristics. It combines modular physics engines, spatiotemporal computation, versioned material science, and full source-method-provenance tracking to ensure every simulated outcome is causally consistent, reproducible, and scientifically traceable. Rendering is strictly a downstream projection of solved physical states in 2D or 3D space, governed by a human-in-the-loop intent and consent system that ensures all simulations are explicitly authorized and auditable. https://roxanneardary.com/physicsmesh-platform/

Fluxara is a physics-native intelligence system for modeling, simulating, validating, and optimizing energy and motion systems. It combines AI-driven design with physics-based simulation and strict constraint enforcement to ensure every generated engine, turbine, or propulsion architecture behaves consistently with real-world thermodynamics and mechanical laws. https://roxanneardary.com/fluxara/

Project SynthesisMotion is an open-source AGPL-3.0+ research framework for adaptive motion intelligence systems. It combines real-time vehicle identity modeling, physics-informed dynamics, and adaptive control with a formal safety verification layer. The system is designed to continuously learn how a physical vehicle behaves, adapt to changes in real time, and enforce strict safety constraints during operation. https://roxanneardary.com/project-synthesismotion/

The Uncertain Machine is an open-source, AI-powered scientific simulation platform where players learn by interacting directly with dynamic models of reality. Instead of memorizing facts, users explore physics, biology, chemistry, and complex systems through experimentation, curiosity, and play. Built for all ages and skill levels, it adapts explanations in real time, turning every interaction into a discoverable, replayable learning experience where science is something you do, not something you read.

DesignFlux is an AGPL 3.0+ open-source engineering platform that combines physics-based simulation, AI-assisted design, manufacturing planning, and collaborative development into a unified ecosystem. Built for engineers, researchers, manufacturers, and innovators, DesignFlux provides modular tools for thermal engineering, aerospace systems, advanced materials, and future technology development, helping teams move from concept and simulation to validation and production.

Mandos is a general purpose differentiable simulator for C++ and Python.

Kit bindings for Box2D v3 - 2D physics engine with rigid bodies, joints, and collision detection

AETHER STAGE is a cinematic spatial intelligence system that transforms filmmaking into a structured, physics-aware, and fully directable simulation. It replaces prompt-based generation with a layered architecture of persistent 360° assets, mass-based spatial constraints, causal narrative systems, and a Director Override Layer that enforces creative intent above all simulation rules.
