In order to efficiently represent complex systems, numerical modelling has to rely on many physical models at a time: an ocean model coupled with an atmospheric model is at the basis of climate modelling; a combustion model coupled with a radiation model allows the computation of a combustion chamber temperature. The continuity of the solution is granted only if these models can constantly exchange information.

OpenPALM is a software allowing the concurrent execution and the intercommunication of programs based on in-house as well as commercial codes.

The OpenPALM team proposes training to the coupler several times each years at CERFACS. Moreover, don't hesitate to contact us directly ( and if you want informations on the coupler, on the instrumentations on the code to couple as well as on coupling algorithms.
