The '''patch test''' in the [[finite element method]] is a simple indicator of the quality of a finite element, developed by [[Bruce Irons (engineer)|Bruce Irons]].
The patch test uses a [[partial differential equation]] on a ___domain consisting from several elements set up so that the exact solution is known. Typically, in [[mechanics]], the prescribed exact solution consists of displacements that vary as linear functions in space (called a constant [[Strain (materials science)|strain]] solution). The elements pass the patch test if the finite element solution is the same as the exact solution.
