Dynamic simulation

Definition

Dynamic simulation is a computational technique used to model the behavior of processes over time, capturing the changes and interactions within a system. It allows for the analysis of transient states in processes, providing insights into how systems respond to variations in inputs or operating conditions. This method is particularly useful for batch and semi-batch processes, where the conditions can change significantly throughout the operation.
