The finite element method (FEM) is the preferred method for solving engineering problems and mathematical models. It originated from the need to solve complex linear and nonlinear structural analysis problems in aeronautical, mechanical, and civil engineering.
FEA investigates changes in the design for weight, cost, manufacturing, performance, or bench marking reasons, and can provide confidence in the designs before undertaking costly regimes and potentially destructive tests. It is beneficial for any project that requires dynamics analysis, strength, or durability. Using sophisticated modeling software, FEA simulates interaction and movement between the parts in a system given a specific set of parameters.
