What is a high-fidelity wind simulation?

Computer aided engineering is helping many industries to optimize process and products. But with an enormous number of new tools and technologies coming up to the market every year, the challenge now is to know how to choose the proper solution. Here’s how you should be selecting a simulation software for flow analysis.

A pollutant dispersion research

These are images from a research conducted in 2016. The goal was to analyze the dispersion of pollutants associated with traffic emissions in an important street of downtown Rio de Janeiro.

When using computational tools to simulate traffic emissions the researchers applied two different methods of simulations: Reynolds-averaged Navier-Stokes (RANS), low-fidelity, and large eddy simulation (LES), high-fidelity simulations. Results showed that small vortices carrying the pollutants are captured only by the LES model. While the RANS model shows exclusively the main characteristics of the flows, providing less reliable information.

Accuracy begins with choosing the right tool

Flow Simulation Software is a powerful tool but choosing the wrong method can produce misleading data. Today, most of the software available run low-fidelity simulation. They don’t require much computational power and are often cost-effective.

Does it mean that high-fidelity simulations are out of reach? Not at all! New software-as-a-service platforms, such as Ingrid Cloud, are allowing anyone to access accurate information, in an easy-to-use and affordable way. But how reliable is a high-fidelity flow simulation? In some cases, a simulation result is 97% similar to how wind flows in real life.

The results of benchmark case studies conducted to compare Ingrid Cloud with wind tunnel or other traditional simulation codes are outstanding! Next time you need a wind analysis, ask us for a high-fidelity simulation with Ingrid Cloud or simply sign-up and do it yourself right now.
