FMI for model exchange and co-simulation
The growing extent of integrated workflows leads to more and more requirements for simulation experts and beginners alike. One of them is the need to flexibly exchange models between various development stages and between different CAE programs in the collaboration between OEMs, suppliers and service providers. This calls for a universal format.
FMI is a tool-independent interface standard for both model exchange and co-simulation of dynamic models.
- FMI for model exchange includes only the code of a model in a functional mock-up unit (FMU), but not the solver, which leaves the target platform to calculate it with its own solver.
- In contrast to that, FMUs for co-simulation come also with their own solver. This allows them to be integrated in other target platforms including optimization tools which do not have solvers for differential equations.
