What Everybody Needs to Know about CAE

ship propeller simulation - CAE with SimScale

 

Computer-aided engineering (CAE) is the broad usage of computer software in analyzing and virtually testing engineering products. With a CAE tool, you can simulate, validate, and optimize products based on numerical analysis’ results.

CAE solutions are used to analyze the robustness and to improve performance of components and assemblies. At the same time, engineering simulation is the major support for design teams in product optimization.

Nowadays, an integration between CAD and CAE has become necessary. Using the SaaS version of both solutions can reduce the differences, offering the possibility of creating a CAD model and run engineering simulations with minimal effort.

A CAE simulation session generally includes 3 main phases:

  • Pre-processing – upload of CAD model, defining the model and environmental factors
  • Running solvers applications – based on simulation analysis algorithms
  • Post-processing – validation of the model and 3D visualization

Main Benefits of CAE 

CAE / simulation for productsThe main benefits offered by CAE / engineering simulation are:

  • Time saving in product development;
  • Improved product quality and reliability;
  • Risk reduction;
  • Possibility to make corrections in the early concept & design phases;
  • Dramatic cost reduction associated to physical testing of prototypes;
  • Keeping the established deadlines in different phases of the engineering workflow;
  • Radical improvement of product quality and reliability thus raising the customer satisfaction level;
  • Product life cycle extension.

CAE Analysis Types

With CAE, we can talk about a large spectrum of engineering simulation CAEanalysis types:

  • Stress and dynamics analysis using finite element analysis (FEA);
  • Thermal and fluid analysis using computational fluid dynamics (CFD);
  • Kinematics and dynamic analysis of mechanisms (multibody dynamics);
  • Acoustics analysis using FEA or a boundary element method (BEM);
  • 1D CAE, or mechatronic system simulation, for multi-domain mechatronics system design
  • Simulation of manufacturing processes like casting, molding and die press forming;
  • Particle simulation as part of a flow industrial process;
  • Multiphysics analysis based on multiple simulation phenomena;
  • Optimization of the product or process.

Large CAE Applicability

All these CAE tools are used in the simulation, validation, and optimization of products with applicability in many industries, including automotiveaerospace, energyplant engineering, industrial equipmentHVAC, electronics, and consumer goods.

Engineering simulation has a wide range of applications, from small components or products to complex appliances, plants, HVAC equipment, and heavy machines. Here are some examples extracted from SimScale Public Projects library:

  • Equipment and machines parts from an industrial process: water flow through a globe valve, centrifugal water pump using the Multi-Reference-Frame method (MRF), acoustic eigenfrequencies of a muffler, sloshing of fuel inside a moving fuel tank, or particle acceleration in a mill wheel.
