Virtual prototyping techniques

Definition

Virtual prototyping techniques refer to the use of computer-based models and simulations to create a digital representation of a product or system, allowing for design evaluation and optimization before physical prototypes are built. This approach integrates various simulation methods, such as finite element analysis (FEA) and computational fluid dynamics (CFD), to assess performance, identify potential issues, and streamline the design process, ultimately saving time and resources.
