since from 2000 About Computer Aided Engineering (CAE)
Computer Aided Engineering is broadly divided into Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and 3D modeling. Finite Element Analysis (FEA) is a computer simulation technique used in engineering analysis, leveraging the finite element method (FEM). FEA predicts failure due to unknown stresses, highlights problem areas in materials, and helps designers compare theoretical stresses with allowable stresses. It significantly reduces manufacturing costs by eliminating the need for building and testing every sample.
Engineering equations for stress and deflection (as defined in codes like ASME, PO5500) rely on assumptions. FEA is invaluable when these assumptions don’t hold or engineering equations don’t apply.
