Computer simulations

Definition

Computer simulations are computational models that use algorithms and mathematical representations to recreate complex systems or phenomena, allowing researchers to study their behaviors and interactions. They serve as powerful tools in understanding dynamics of celestial bodies and processes involved in planetary formation and migration, providing insights that are difficult or impossible to obtain through direct observation alone.
