Co-simulation is one technique for coupling different simulators into one coherent simulation. Existing cosimulation applications are often capable of interconnecting two specific simulators where a unique interface between these tools is defined. However; a more general solution is needed to make co-simulation modeling applicable for a wider range of tools. Any such solution must also be numerical stable and easy to use to be applicable by a larger group of people.

In this work the concept of meta-modeling is applied to mechanical co-simulation. Several tool-specific simulation models can be integrated and connected by means of a meta-model; where the meta-model defines the physical interconnections of these models.

A general meta-modeling process is described that represents the basis for this work. A meta-modeling language (MML) has been defined to support the modeling process and store the meta-model structure. Besides elements for physical interconnections; etc.; the language also defines graphical elements that can be used for meta-model visualization. All proposed solutions are general and simulation tool independent.
