The Finite element method (FEM) is a powerful technique
originally developed for numerical solution of complex
problems in structural mechanics, and it remains the method
of choice for complex systems. In the FEM, the structural
system is modeled by a set of appropriate finite elements
interconnected at points called nodes. Elements may have
physical properties such as thickness, coefficient of
thermal expansion, density, Young's modulus, shear modulus
and Poisson's ratio.
