fmi2

A universal mechanism for implementing Functional Mock-up Units (FMUs) in various languages

A simple, fast and easy to use co-simulation engine.

Simplified C-Interface for fmi2 models. Includes .net wrapper.

One compiler for every engineering model: SysML v2, Modelica, STEP, and legacy proprietary formats, running in your browser.

Generate standard form system FMUs through CLI.

A tool to encapsulate machine learning models defined using the ONNX format to Functional Mock-up Units (FMU) defined by the FMI standard.

A collection of FMU sensor models and NMEA sender written in C++

modelica kalman filter library

Community continuation of FMI4j focused on multiplatform native runtime support for JVM FMU import.

Simulate Co-Simulation FMUs in Unreal Engine 4. (Fork with Linux support, improved build system, more functionality)

A guarded calloc/free to be used primarily by other drivers that handle FMI2 standard compliant libraries.

Agentic FMI turns Claude Code into a simulation assistant for FMI models (FMUs). Ask in plain language: inspect an FMU, simulate and compare runs, build new FMUs from Python or Modelica, connect them into a closed loop, and steer a live simulation while a pane inside Claude Code charts it. Claude reads compact results (metrics and plots)

Automatic FMU Approximation Tool

Golang wrapper for building FMI 2.0 compatible shared libraries in Go.

FMI2/3 modelDescription.xml parser

A lightweight library for FMU binary loading
