The long-term goal of the Dynamo Working Group is to produce a series of ever more efficient, massively parallelized, well-documented community dynamo models for broad usage by the dynamo community. With these HPC models, it should be possible to significantly decrease the fluid viscosity in dynamo models (e.g., by at least two orders of magnitude). This will enable transformative studies of fully-developed turbulent dynamo action as occurs in Earth’s core. At present, we are developing two new dynamo codes, Calypso and Rayleigh, and carry out a community benchmarking exercise aimed at identifying the best routes forward in developing next-generation dynamo modeling frameworks.
