One of the good reason to use simulation in an experiment is to predict the outcome of an event in the real world.
Explanation:
Simulation is a programming software which helps in imaging or easy understanding of any experimental concept virtually. For example, if we enter the details regarding an element, the simulation can draw the structure of that element. Also it may predict the working of the bonds and other parameters in different conditions based on classical and quantum theoretical laws. So a researcher can compare the results obtained from simulation and also from experimental results.
In other words, simulation will help a researcher to have an assumption about the behavior of the sample in real world conditions.
