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.
