FELiCS - The linear flow solver.

Developed at the Institute for Fluid Dynamics and Technical Acoustics at TU Berlin, FELiCS is an open-source simulation code designed for researchers and engineers tackling complex flow problems. Its finite element discretisation of the linearised flow governing equations enables accurate modeling of intricate geometries and diverse physical scenarios — from combustion dynamics to aerodynamic instabilities and water turbine flows and many more.

Versatile. Open. Research-Driven

FELiCS breaks away from the limitations of traditional linear finite-difference solvers, offering a modular, general-purpose tool trusted in over 30 scientific publications.

The Modular Non-Invasive BCI Engineering Platform is an open-source, AGPL-3.0+ neuroengineering framework designed to unify wearable brain-computer interfaces, hardware abstraction, and real-time neural decoding into a single modular system. It enables developers to build, simulate, and deploy EEG-based applications through interchangeable wearable and hardware modules, supported by machine learning pipelines, sleep and dream state analysis, hardware development tooling, and legal assurance systems for design validation and compliance. https://roxanneardary.com/modular-non-invasive-bci-engineering-platform/

LAVE (Low-Altitude Vehicle Experiment) is an open-source research platform exploring human-scale hover in the sub-meter regime using distributed electric thrust, real-time stabilization, and fully transparent hardware and software systems. Built for reproducibility and experimentation rather than productization, it focuses on measuring the unstable transition between ground contact and sustained flight, with all telemetry, failures, and design iterations openly shared as part of the research process. https://roxanneardary.com/lave/

KineticKind is an open-source SUV platform designed to make entering and exiting a vehicle safe, comfortable, and dignified through intelligent seat-assist technology. By combining rotating lift seats, accessibility-focused engineering, and a fully open development model, the project reimagines mobility around real human movement rather than mechanical constraints.

CIRRUS GRID is a modular atmospheric intelligence network that transforms airspace into a distributed, self-healing communication and compute system. It operates across ground, low-altitude autonomous swarms, and stratospheric platforms to enable persistent connectivity, real-time sensing, and adaptive coordination without reliance on fixed terrestrial infrastructure. https://roxanneardary.com/cirrus-grid/

Adaptive Materials Engine (AME) is an open-source engineering intelligence system that helps designers, engineers, and makers replace plastic components with locally sourced, economically viable, and mechanically equivalent or superior materials. When direct substitution is not possible, AME automatically redesigns the system to eliminate plastic dependency while optimizing for cost, performance, and sustainability. https://roxanneardary.com/adaptive-materials-engine/

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/

PatentCortex is a modular AI-powered patent intelligence engine that converts complex vehicle and machinery patents into structured, searchable engineering data.
