FEM - short version

Meaning 1:

Finite element method is a numerical system that assists with engineering calculations by dividing an object in smaller parts, known as finite elements. The properties of these parts are mathematically formulates to obtain the properties of te entire object.

Meaning 2:

Finite Element Model(ing).

FEM - long version

Meaning 1:

The finite element method (FEM) (sometimes referred to as finite element analysis (FEA)) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The solution approach is based either on eliminating the differential equation completely (steady state problems), or rendering the PDE into an approximating system of ordinary differential equations, which are then numerically integrated using standard techniques such as Euler's method, Runge-Kutta, etc.
