Executive Summary

We are developing time integration software that accommodates widely varying timescales commonly found in multiphysics simulations, such as atmospheric climate modeling, where cloud microphysics, fluid dynamics, and ocean currents each evolve at different rates. This research supports national missions that rely on complex simulations, such as energy and nuclear security.
