However, the educational implementation of this tool is still directly made with engineering software which has a primitive educational context, thereby preventing students to understand challenging concepts. Multiphysics CFD simulations, one of the most applied computer-assisted process engineering (CAPE) tools, have been a maturing method increasing comprehension of engineering design and analysis.

They share the common approach that discretizes the Navier-Stokes equations into a system of algebraic equations. There are other kinds of numerical methods, for example, the spectral method and the spectral element method, which are often used in CFD. This chapter presents the basics of the finite-difference and finite-element methods and their applications in CFD. If it is used correctly, it can provide useful information cheaply and quickly. CFD is merely a tool for analyzing fluid-flow problems. Different techniques are available for this conversion. The key to various numerical methods is to convert the partial different equations that govern a physical phenomenon into a system of algebraic equations. The most common sources of error are mentioned in the chapter. Because many potential sources of error may be involved, one has to be very careful when interpreting the results produced by CFD techniques. CFD has increased in importance and in accuracy however, its predictions are never completely exact. Computational fluid dynamics (CFD) is a science that, with the help of digital computers, produces quantitative predictions of fluid-flow phenomena based on the conservation laws (conservation of mass, momentum, and energy) governing fluid motion. This chapter focuses on computational fluid dynamics. Hu, in Fluid Mechanics (Fifth Edition), 2012 Publisher Summary
