The OASIS coupler ant its applications

Coupling numerical models is a central issue in the climate research community and in other research fields such as electromagnetism, computational fluid dynamics (CFD). Ideally, the coupler, i.e. the software interface between the different models, should allow the realization of coupled simulations on different types of platforms at a minimal cost, the testing of different coupling algorithms (e.g. time strategy or interpolation methods), and an objective intercomparison of coupled models by changing some or all component models. One can see right away that these specifications strongly suggest modularity as the key concept in designing the interface software structure.

OASIS was written to answer these requirements.

OASIS main tasks are:

to exchange, in a synchronised way, coupling fields between the component models whcih remain independant executables ;
to perform the transformations and 2D interpolations needed to express, on the grid of the target model, the coupling fields produced by the source model.

This is done in a modular way in order to allow coupling any number of models and flexibility in the field treatment.
