Functional mock-up interface V2.0 (June 2014)

Protocol used in automobile industry supports co-simulation model data exchange.

The functional mock-up interface for model exchange and co-simulation (FMI) was originally developed by Daimler (Mercedes-Benz) to enable the exchange of simulations with suppliers. The interface has had some take up in oil and gas as witnessed by a Statoil presentation at the 2012 Modelica conference of a case study on the estimation of the gas-oil ratio of an offshore production facility.

A candidate release of V2.0 of the FMI spec was released this month for prototype implementations to get feedback from the user base. The spec has two main fields of application, model exchange and co-simulation. FMI models are described by differential, algebraic and discrete equations and can generate C code for use in other modeling and simulation environments. Models can be very large for use offline or small for embedded control systems on micro-processors.

The interface standard allows for coupling of simulators in a co-simulation environment with data exchange at discrete communication points. A master algorithm controls data exchange between subsystems and the synchronization of all simulation solvers (slaves). More from FMI.
