Dymola can be easily interfaced to other software.
It is possible to interface Dymola and the SIMULIA tools Abaqus, iSight and Fiper.
This can be used for e.g. co-simulation. The image shows the animation of a yacht model riding a wave, with control surfaces modeled in Dymola.
An example of Dymola and Abaqus co-simulation of a high fidelity anti-lock brake system is presented in this paper from the Modelica Conference 2009:
