Modelica Libraries

A collection of free and commercial libraries.


This page contains a list of Modelica libraries (both free and commercial) - see the short overview of libraries for details.

The listed libraries are sorted by:

  • Free standard conform libraries developed by the Modelica Association
  • Free other libraries developed by the Modelica Association
  • Free libraries provided by users of Modelica
  • Free older libraries developed by the Modelica Association (deprecated)
  • Commercial libraries

Note that the usage of a Modelica library requires a Modelica simulation environment, see the tools page.

The libraries from the Modelica Association and most free libraries can be used in commercial products according to The Modelica License.
