Abstract:

The Hierarchical MultiScale Framework (HMS) facilitates the development of new multiscale models from the assembly of individual at-scale model components. A runtime system in HMS adaptively evaluates the at-scale models and performs data extraction necessary for scale-bridging between components. Existing at-scale models can be incorporated into HMS without modification allowing users to leverage complex and mature software codes. This User’s Guide serves to document the steps necessary for development of new multiscale models with HMS. It includes an overview of the mathematical approach to multiscale modeling that HMS adopts, the steps necessary to incorporate at-scale models into HMS, use of the HMS Broker to perform at-scale model evaluation and data extraction, and use of the adaptive surrogate modeling capabilities implemented in HMS.
