3 FINITE ELEMENT METHODThe finite elements (FEM) method is particularly useful when a robust approximation is sought to solve partial differential equations on an inhomogeneous mesh. Solid mathematical foundations and a great deal of generality allow for different implementations that are only sketched in the first section: an example given for the advection-diffusion equation, for example, shows how the Crank-Nicholson method described in the previous section is only a particular case of a finite elements scheme.

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.
