Model Coupling
- Crossing the scales
- Modularity
- Flexibility
- Performance
- Physical processes take place on a domain and at certain scales in time and space
- Simulation models are described by the Submodel Execution Loop
- Given two models and their domains and scales, we can decide which coupling template to use to connect them
- An MMSL diagram can be used to visualise a complete coupled simulation
- MUSCLE3 implements the MMSF theory, using the same terminology and MMSL for configuration of the coupled simulation
- First analyze your code to find the Submodel Execution Loop structure
- MUSCLE lets the submodels communicate through messages, containing model states and simulation times
- Models may differ in which ports they have and when they send and receive
- The yMMSL file discribes components, conduits, settings and resources
- Running the coupled simulation can be done from a Python script
- For larger simulations and C++ and Fortran, submodels run as separate programs via the MUSCLE3 manager
