A computer model is a representation of a real-life system or situation, such as the workings of a nuclear reactor or the evacuation of a football stadium. A collection of rules is created to study ...

The only way to predict the day-to-day weather and changes to the climate over longer timescales is to use computer models. These models solve complex mathematical equations that are based on well ...

A model or simulation is only as good as the rules used to create it. It is very difficult to create an entirely realistic model or simulation because the rules are based on research and past events.
