If a car is not aerodynamically stable, it could behave erratically at high speeds. Fuel economy is one of the most important aspects of modern cars. These functions are all vital in the design of a car. For cars, modelling aerodynamics is important to calculate fuel economy, stability, the noisiness of the cabin, the cooling of the engine, and the performance of the engine. Aerodynamics Modelingįigure 1: simulation of aerodynamics around a car Īerodynamics is a commonly modeled field of physics. In this section, we introduce some examples of problems that can be solved with Big Data Science and Physics simulation. Thus, quantum computers must be used to simulate these problem, and that is an entirely different topic. Many phenomena, when simulated with conventional computers, would experience an exponential decrease in performance as the number of particles in the system increases. Another example of something which cannot be simulated with conventional computers is some areas of quantum physics. Then, if the universe is infinite, computers can not and will not be able to simulate the entire universe. This would be a problem for computers, which can only simulate a finite area. According to some theories the universe is of infinite size. An example of such an intractable problem would be simulating the entire universe. Very few problems are not possible to be simulated. 4.2.2 What to Simulate with Physics EnginesĪlmost anything can be simulated in a physics engine. More specific information and what physics engines the NOAA uses are available on their website ( Here is a good example ). The NOAA (National Centers for Environmental Information) oversees the standardization of numerical weather prediction. This is done with numerical weather prediction. Physics engines can also be used to predict the weather quite effectively. This technique is used by automakers during the design phase of a car to determine if the chassis should perform adequately when tested in the real world.
This is done through a field of simulation-based physics known as crash simulation. Have you ever been in a car or a plane? Have you experienced the weather? For one, simulation-based physics is used to test the safety and effectiveness of cars and planes. These simulations will be discussed more in Section 4.2.4.Īlthough it may seem that simulation-based physics is far away from everyday life, it is closer than you may think. An example of simulation-based physics is easy to find within the PhET simulation website. This specific physics engine is utilized in many games including the Age of Empires series, the Battlefield series, and some Call of Duty games. Physics simulation is also synonymous with physics model. This video is showcasing physics simulations. There is a video of the Havok Physics engine running on the front page of their website.
However, it is still a good example of an accessible physics engine. The Havok engine is a physics engine specifically made for video games and not scientific research. The first is a type of software, the second is what occurs when you run a physics engine, and the third is a field of study.Īn example of a physics engine would be something like the Havok physics engine. Each of these terms such as physics engine, physics simulation and simulation-based physics have different meanings. This field, also referred to as physics simulation, deals with many topics that are studied within physics, but specifically how they are adapted to be simulated within a physics engine. The existence of virtual simulation brought about a field of simulation-based physics. These simulations could be in the real world, in a virtual environment by using a physics engine, or partially in both. A physics simulation is a recreation of a real-world occurrence.
