Computational Fluid Dynamics (CFD) and Finite Elements Analysis (FEA) are two important simulation tools that are used in engineering design projects on a regular basis.

With CFD, various design ideas can be simulated in a very short period of time, and designers can go through several optimisation loops until a desired solution is found.  Some of the advantages of using CFD are:

  • optimisation of flow and temperature distribution within the system

  • minimisation of pressure drops in manifolds and surroundings

  • optimisation heat transfer rate within fluids or fluids and solids

  • detailed elaboration of electro-chemistry simulations, gas compositions, etc.

  • combustion and emissions control


There are however cases where using CFD as a tool is more time and energy-consuming  than it is worth.  It is therefore recommended that one consult with experts before embarking on  CFD analysis.

If a system under development has to withstand heavy loads, vibration or thermal shocks, it is often recommended to perform FEA simulations as well. Some of the advantages of using FEA include:

  • minimising risk of failure in pieces under tension

  • optimising design to avoid cracks and breakage

  • minimising creep and fatigue issues in pieces operating at high temperatures

Depending on the project under study, sometimes it is beneficial to combine both CFD and FEA analysis to perform co-simulations, which can be further improved with Multi-Disciplinary Optimisations (MDO) in order to derive an optimal solution.
