In addition to transforming visualization, GPU acceleration has fundamentally changed simulation and analysis processes within design software. Complex simulations, which once required painstaking computations on CPU-based systems, are now executed swiftly through parallel processing in GPUs. Several aspects illustrate how GPU advancements have redefined these tasks:

• Complex Geometry Handling: GPUs efficiently process and render intricate models, ensuring that even the most detailed geometric designs are managed effectively.
• Accelerated Simulation: Applications performing finite element analysis (FEA), computational fluid dynamics (CFD), and thermal simulations see substantial performance improvements, making iterative testing more viable.
• Seamless Integration: Leading design software companies integrate GPU acceleration into their release cycles, continuously updating tools to take advantage of new hardware capabilities. This integration has resulted in a design environment where simulation and visualization occur concurrently, allowing for immediate evaluation of design parameters.
