1. A method of processing multiple submodels of a partitioned model, the multiple submodels including a first submodel and a second submodel, said method comprising: coupling a first submodel and a second submodel of a partitioned model, said coupling comprising: providing a first coupler interfaced with said first submodel; providing a second coupler interfaced with said second submodel; interfacing said first coupler and said second coupler, said interfacing comprising providing a buffer between said first coupler and said second coupler; and collectively processing said first submodel and said second submodel, wherein said first submodel and said second submodel communicate employing said first coupler, said buffer and said second coupler.
