WebApr 8, 2024 · What Are First- and Second-Order Elements? Before we begin, it is important to remember exactly what a finite element model represents: a discretized depiction of a continuous system. Because this representation is comprised of discrete points (integration points) at which calculations are performed, values must be interpolated … Webthe finite element method (FEM). • In the FEM, the PDE’s are approximated as linear equations on the element level, i.e. a local stiffness matrix, K, and a local right hand side …
