#simulation

A backend-agnostic harness for regression-testing time-dependent system behavior — five simulators, six tolerance-based comparison modes, and an interactive report that doubles as the authoring surface for acceptance criteria.

Three tools around one capture contract — an Unreal Engine 5 plugin that records synchronized, nanosecond-timestamped multi-modal sensor data (RGB, depth, segmentation, DVS, optical flow, IMU, LiDAR, thermal, cubemap); Forge, the Python analysis and fusion toolkit that reads those captures; and rsviewer, a browser viewer that puts every stream on one timeline.

A Modelica library for system-level dynamic simulation of nuclear and other thermal-hydraulic energy systems — fluid networks, heat transfer, heat exchangers, nuclear kinetics, media, and controls in one reconfigurable package. Started at ORNL in 2017, still moving, Apache-2.0.
