Which item best describes technology typically required to run simulations?

• A. Internet on a tablet
• B. A smart phone, a portable 3D scanner, and a headset
• C. A computer system, CAD 3D software, and a robot
• D. A computer system, graphics display software, user interface, joystick, mouse, keyboard or custom control input devices

Answer: (D)

Running simulations requires a capable computer, the ability to render graphics, and an interface to interact with the model. A computer system provides the processing power and memory to compute the simulation steps. Graphics display software handles rendering the scene so you can see the evolving model clearly. A user interface gives you menus, controls, and parameters to adjust the simulation’s settings. Input devices—like a mouse, keyboard, joystick, or custom controllers—let you manipulate variables or drive actions in real time. The other options don’t consistently include all of these core elements: one emphasizes network access or mobile hardware, another combines sensing devices with immersive gear, and another pairs design tools and hardware but omits robust display and input capabilities needed to run and interact with a simulation.
