Computational Wind Engineering with CFD in the Cloud

CFD in the Cloud

Engineers consider computational fluid dynamics (CFD). They often think of internal flow (like in pipes) or external flow (like in a river) (e.g., aircraft aerodynamics). But computational wind engineering (CWE), or wind engineering, is an area where CFD is used much more. This is because wind engineering is complicated, and there is more and more computing power available. 

Most of the time, these studies are done in expensive wind tunnels and rarely online. They look at everything from how comfortable the wind is to how well it moves air and how the wind affects the load on a building. Also, these practical studies are only done in sporadic cases, and even then, they are only done in a limited way. One must also look out for CFD Training.

Things to Think About Before Starting a Wind Engineering Simulation that Uses Computers

Before starting a wind simulation, the first thing to consider is the end goal and how it will be set up. Is the wind comfort of a particular area to be looked at for incompressible external flow? Cross-ventilation to figure out how well ventilation works inside a building? The first step in ensuring that the wind engineering project can be done as quickly as possible is to figure out what needs to be analysed.

Spatial Scales

The next important thing to consider when deciding what to model and what not to model is the size of the area. If the correct spatial scale is not chosen or is omitted, simulations may not be able to represent the naturally built environment accurately.

Every possible scale of space would be available in the simulation in an ideal world to be as realistic as possible. This is impossible and a very inefficient way to do things. So, it’s essential to make reasonable assumptions. Most of the time, micro and building scales environments are modelled and simulated based on assumptions about what goes into them. On the microscale, the average wind speed from a particular direction would be used, while on the building scale, a simple velocity inlet at an opening with the wind speed at that height would often be enough.

Things to Think About with Software and Hardware in Wind Engineering

Wind engineering and CWE simulations need to pay special attention to software and hardware. Due to the large scales and large, complex meshes involved, there needs to be a lot of attention paid to how much computing power is available. Simulations are often done on a smaller scale, so adjustments need to be made to ensure the effects are still shown correctly on a smaller scale.


Today, there is a lot of computing power around, so it is possible to do full-scale simulations of complex environments. SimScale is an excellent example of this because it has up to 96 computing cores and can run simulations in parallel. This is a massive help to anyone who wants to do full-scale, complex computational wind engineering simulations. For fluid dynamics analysis, the fact that this kind of computing power is available in the cloud and can be accessed with a simple web browser makes it even less important to spend money on expensive infrastructure.
