The Multiscale Coupling Library and Environment (MUSCLE) couples heterogeneous computational multiscale models of multiple disciplines. Its aim is to provide a uniform platform to implement submodels using varying programming languages, execute them on heterogeneous machines and couple them across diverse networks. In addition, it considers the temporal and spatial scale at which the submodels are operating.
The library contains Java, and C and C++ APIs, allowing developers to easily use Java code or C, C++ or Fortran as a language of choice for model implementation.
