⩥ What is a Node? Answer: A point in the finite element mesh where
unknown quantities are defined
⩥ What is an element? Answer: A connection between nodes that
represents a portion of the physical domain
⩥ What is a mesh? Answer: A collection of nodes and elements
⩥ What is the Finite Element Method (FEM)? Answer: A numerical
technique used to approximate solutions to boundary value problems by
dividing the domain into smaller elements and solving for unknown
quantities at discrete nodes
⩥ What is the Rayleigh-Ritz Method (RRM)? Answer: An approximate
solution technique where the displacement field is assumed using trial
functions with unknown coefficients, which are determined by
minimizing total potential energy
