Simulation software

Definition

Simulation software is a tool that allows users to create digital models of real-world processes, systems, or phenomena to analyze their behavior and performance under various conditions. This software is particularly important in chemical engineering as it helps predict how changes in variables can affect outcomes, facilitating better decision-making and design optimization.
