In this paper, we present an abstract model to steer legacy coupled simulations that follow the Multiple-SPMD paradigm or the client/server paradigm. This model extends our previous work for the steering of classical SPMD simulations. It describes the application in terms of execution flow, complex distributed data objects and user interactions. Thanks to this abstraction, we define a coordination algorithm that allows us to efficiently interact with the simulation and to overcome the time-coherence problem raised by coupled simulations.
