What is CAE?

CAE is the abbreviation for Computer Aided Engineering and describes computer-aided development. This includes all variants of product development processes that can be carried out on the PC, such as:

  • CAD (Computer Aided Design)
  • FEM (Finite Elemente Method)
  • CFD (Computational Fluid Dynamik)
  • MKS (Multibody Simulation)
  • CAM (Computer Aided Manufacturing)
  • CAQ (Computer Aided Quality)
  • CAPE (Computer Aided Process Engineering)
  • DMU (Digital Mock-up)
  • Human Modeling
  • Digital Twin

CAE processes are divided into preprocessing, solver and postprocessing. During preprocessing the system is built up (e.g. geometry), the physical properties are defined (e.g. material models) and boundary conditions are determined (e.g. loads, restraints etc). The solver then solves the mathematical problem using numerical methods. In the postprocessing the evaluation and visualization of the results takes place.

Advantages of CAE:

  • Lower product development costs
  • Reduction of product development times
  • Saving of prototype tests
  • Help with design decisions at an early stage of development
  • Lifetime predictions without complex component tests
  • Risk minimization through increased component understanding
  • Visualization options
