What term describes using computer simulations in coaster design?

The term that best describes using computer simulations in coaster design is CAD, which stands for Computer-Aided Design. CAD software enables designers and engineers to create detailed 2D and 3D models of roller coasters, allowing them to visualize and refine their designs before construction. This software incorporates complex calculations and simulations to analyze the structural integrity, ride dynamics, and safety features of the coaster.

While 3D modeling is a component of CAD, it is a broader term that can apply to various fields beyond coaster design. Virtual reality, though immersive and useful for experiencing designs, does not inherently involve the design processes focused on technical specifications and engineering analysis. Simulation software also refers to a wider range of applications and does not exclusively denote the comprehensive design-focused capabilities of CAD in the context of roller coaster engineering.
