Abstract

The Functional Mock-up Interface standard allows to generate stand-alone sub-systems which can be simulated and verified individually. In this paper we present a design of a model aggregation which allows to simulate several Functional Mock-up Units as a coupled model. The formulation is based on Assimulo as a numerical integration environment. Assimulo problem classes are extended to a class for aggregated problems which collects information provided by the Functional Mockup Units through the tool PyFMI together with Python based problem classes defined by Assimulo. This allows to set-up test environments of complex models composed of several sub-systems.
