Simple

Definition

In the context of computational fluid dynamics (CFD) for underwater robotics, 'simple' refers to the approach or method that emphasizes ease of understanding and implementation in solving fluid flow problems. This often includes models and algorithms that are straightforward and manageable, making it easier to simulate and predict fluid behaviors without overwhelming complexity. The use of simple methods allows engineers and researchers to focus on core principles and fundamental interactions within the fluid environment, leading to practical applications in robotic design and performance.
