ELI5: Explain Like I'm 5

Performance simulation

Do you like to play with your toy cars? Imagine if you could make a big computer game with cars that drive super fast and race each other. But before you can make the game, you need to make sure it will work and be fun to play. That's where performance simulation comes in!

When people make big things like airplanes, cars, or buildings, they use performance simulation to figure out how they will work without actually building them first. It's like playing with a toy car, but with a computer instead. The computer lets you make a pretend version of the thing you want to build so you can test it out and see what happens.

To do this, people use special computer programs that can make a pretend version of the thing they want to build. They can put in all kinds of information like how fast something will go, how much weight it can carry, or how much wind it can handle. Then, the program will show what will happen when they use it.

For example, imagine we're making a race car. We can use a performance simulation program to see if it will go fast enough to win the race. We can test different things like how big the tires are, how powerful the engine is, or how slippery the car is on the track. The program will tell us how fast the car will go, how well it will handle turns, and if it will break down.

Performance simulation helps people figure out what will happen before they build something, which saves time and money. It's like playing with toy cars, but it can help make real things!
