Free (standard conforming) library to model mechanical (1D/3D), electrical (analog, digital, machines), magnetic, thermal, fluid, control systems and hierarchical state machines. Also numerical functions and functions for strings, files and streams are included.

Free (standard conform) library that is intended to model electrical power systems at different levels of detail both in transient and steady-state mode.

Free (standard conforming) library for interface definitions and architectures for vehicle system modeling

Free (standard conforming) library to precisely define and synchronize sampled data systems with different sampling rates. It provides convenient to use blocks to utilize the new synchronous language elements introduced in Modelica 3.3.
