Abstract

Numerical simulations are increasingly used in most industries. So why do companies still spend so much money for experimental testing? I would like to give some explanations about the reasons of building expensive test equipment, which is much more expensive than software for numerical simulations, and how to utilize the different methods.

Will the customer be satisfied with the performance and the quality of the product? This is one of the major tasks during the development process. Today, numerical simulation and experimental testing are used to qualify products in different stages of the development process. Simulation models or experimental models are designed to simulate the real behavior of the product in the hand of the customer. In this context, it should be emphasized that experiments try to simulate customer usage, too. Both methods have to be validated.
