The package Modelica® is a standardized and free package that is developed by the "Modelica Association Project - Libraries".

Its development is coordinated with the Modelica® language from the Modelica Association, see https://www.Modelica.org. It is also called Modelica Standard Library. It provides model components in many domains that are based on standardized interface definitions. Some typical examples are shown in the next figure:

For an introduction, have especially a look at:

This version of the Modelica Standard Library consists of

that are directly usable (= number of public, non-partial, non-internal and non-obsolete classes). It is fully compliant to Modelica Specification version 3.4 and it has been tested with Modelica tools from different vendors.
