Editing Computer experiment (section)

==Background==
[[Computer simulation]]s are constructed to emulate a physical system. Because these are meant to replicate some aspect of a system in detail, they often do not yield an analytic solution.  Therefore, methods such as [[discrete event simulation]]  or [[finite element]] solvers are used.   A [[computer model]] is used to make inferences about the system it replicates.   For example, [[climate models]] are often used because experimentation on an earth sized object is impossible.
