javaFMI is a Java Library for the functional mock-up interface (or FMI). FMI defines a standardized interface to be used in computer simulations. The FMI Standard has beed developed by a large number of software companies and research centers that have worked in a cooperation project under the name of MODELISAR. This library addresses the connection of a java application with a FMU (functional mock-up unit).

The newest version!
