Explore a Julia-based fluid dynamics library focused on oceanic settings in this conference talk from JuliaCon 2024. Discover Oceananigans, the foundation for the ocean component of CliMA's Earth System Model. Learn about the library's implementation strategy, emphasizing flexibility, usability, and GPU performance optimization. Understand how this approach creates a generalized framework easily extendable to various physical parameterizations and model components. Examine specific examples, including the implementation of sea-ice and biogeochemistry components. Time permitting, witness the library's user-friendly nature through a demonstration of integrating a neural network into Oceananigans' hydrostatic model.
