Hybrid Simulations

Definition

Hybrid simulations are computational models that integrate different simulation techniques to study complex systems, combining both kinetic and fluid models to capture a wide range of physical phenomena. This approach allows researchers to analyze interactions in environments like induced magnetospheres and cometary dynamics, where both large-scale fluid behavior and small-scale particle interactions are important.
