Why simulate

A CFD simulation is often used to develop or improve a product. It is also a good way to demonstrate to third parties that your product or installation works the way you say it works. This allows you to sell or get approval for your product.

A CFD simulation is a more detailed calculation method compared to standard design calculations. In many cases this can lead to (financial) savings.

The results of a CFD simulation are often appealing and therefore also commercially interesting. They give a high-tech feel to your product and help to show how your product works in an understandable way.

You can perform a CFD simulation during the design phase itself. This way you can optimize your product at an early stage and thus save on testing costs and possibly avoid unwanted design re-iterations at a later stage which can cost heavily.

Simulations are an alternative to a practical test or measurements with a number of advantages:

  • In some cases it is simply not possible to test in real life because it is impossible or because it is too expensive, too complex or too dangerous.
  • A CFD simulation is usually faster compared to (setting up) a test.
  • A CFD simulation is usually cheaper than a test.
  • A CFD simulation is often more practical than a test because it is more controllable. You can always test under the same conditions and the test by means of CFD is always exactly repeatable.
  • In a CFD simulation you can measure any variable anywhere, even afterwards if the test has already been performed. Since a CFD is a virtual environment, measuring variables is equivalent to a non-intrusive test environment, thus not affecting the test itself.
  • In a CFD simulation you don't need to rescale the products, which is often necessary for a test. You don't have to convert the obtained results to full scale with all associated uncertainty.
