Finite Element Analysis Why FEA? - CAE Users
1 Finite Element Analysis Numerical method of solving engineering problems. May be applied in: structural heat transfer fluid flow We will limit discussion to structural FEA? Used in problems where analytical solution not easily obtained. Mathematical expressions required for solution not simple because of complex: geometries loadings material propertiesFEA: Basic concept Replace continuous geometry with a set of objects with a Finite number of DOF Divide body into Finite number of simpler units ( elements ). elements connected at nodal points points common to two or more adjacent elements set of elements referred to as mesh FEA vs. analytical methods Analytical methods involve solving for entire system in one operation.
1 Finite Element Analysis • Numerical method of solving engineering problems. • May be applied in: – structural – heat transfer –fluid flow
