The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system. Simulation is used in many contexts, including the modeling of natural systems or human systems in order to gain insight into their functioning. [1] Other contexts include simulation of technology for performance optimization,modeling [1]technology safety engineering, testing, training and education. Simulation can be used to show the eventual real effects ofsafety engineeringtestingtrainingeducation alternative conditions and courses of action. Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes.

After one 400 kilometers two extreme wind gusts made the car uncontrollable with the crash as consequence. At that time we were driving 110km/h, only a few seconds away from the first place. With that speed we ran into a tree. Luckily the pilot could leave the vehicle unharmed thanks to the solid structure of the car, that was calculated with your software. For both the pilot and the rest of the team this was the end of a dream. More than 18 months of hard work vanished in less than one second. Our goal was to build the best solar car ever. Although we didn’t finish the race and have no prove, we still believe that we, in some way, accomplished that. The world’s largest universities saw a fearsome opponent in us. We are really thankful that a company as Altair wants to cooperate with us. Thanks to your software, your trainings and your willingness to answer all of our questions, we were able to build a light and safe car. All the hours of work really saved a human life. Although the crash meant the end for us, we are really looking forward to put together a new team. Hopefully they can count on the same partners as we did. ing.
