Industrial simulation is the process of digitally replicating a physical system or process in order to analyze and understand its behavior. It involves the use of computer simulations to model the components and interactions of a system in order to predict its performance. Industrial simulation can be used to test the design of a system and optimize its performance, predict its failure points, and create virtual prototypes to test before constructing physical ones. It can also be used to analyze processes and optimize production lines and manufacturing processes.
