Who uses numerical modeling?
Numerical models have been used in weather prediction for the last several decades. They are also applied in many fields in sciences and engineering—for example, computational fluid dynamics models are used to study the motion of flow under various conditions. Numerical models are also used to study the stress of a construction, the motion of stars and satellites, the environmental response to the change of trace gases, and even the climate of prehistorical times. Because we can change the initial and boundary conditions to study the results and mechanisms involved in different conditions, numerical models are extremely versatile, and we can simulate experiments on the computer that would be impossible to set up in the real world.
