Simpack
Simpack is a general multibody system simulation (MBS) software enabling analysts and engineers to simulate the non-linear motion of any mechanical or mechatronic system. It enables engineers to generate and solve virtual 3D models in order to predict and visualize dynamic motion, coupling forces and stresses. Simpack is used primarily within the automotive, engine, HIL/SIL/MIL, power transmission, railway, and wind energy industrial sectors, but can be applied to any branch of mechanical engineering. Simpack simulation software is particularly well-suited to high frequency transient analyses, even into the acoustic range. Simpack was primarily developed to handle complex non-linear models with flexible bodies and harsh shock contact.

Prism
Prism is Navier AI’s desktop AI engineering platform for hardware, mechanical, aerospace, and other engineering teams. It combines parametric CAD, 3D viewing, physics simulation, code editing, and reporting in one application. Users can describe a part or study in natural language, create or refine CAD, and use AI agents to configure and run physics solvers, write scripts, inspect results, and generate plots, dashboards, reports, or slides. The solver catalog includes 12 solver families, such as OpenFOAM, SU2, CalculiX, Elmer, Project Chrono, and OpenModelica, plus Navier AI’s Ferro solver. Engineers can import STEP files, review scripts, meshes, and solver inputs, and run multiple agents in parallel to explore designs. Prism installs on Windows, macOS, and Linux; local solver workflows run on the user’s computer. The agent requires an internet connection and sends the content it reads to Navier AI’s model backend. Optional cloud compute can run approved solver jobs.

MPCPy
MPCPy is a Python package that facilitates the testing and implementation of occupant-integrated model predictive control (MPC) for building systems. The package focuses on the use of data-driven, simplified physical or statistical models to predict building performance and optimize control. Four main modules contain object classes to import data, interact with real or emulated systems, estimate and validate data-driven models, and optimize control input. While MPCPy provides an integration platform, it relies on free, open-source, third-party software packages for model implementation, simulators, parameter estimation algorithms, and optimization solvers. This includes Python packages for scripting and data manipulation as well as other more comprehensive software packages for specific purposes. In particular, modeling and optimization for physical systems currently rely on the Modelica language specification.
