Computational fluid dynamics (CFD) aims to analyze and solve fluid mechanics problems within a variety of practical contexts. In particular, CFD approximately solves the mathematical models in fluid mechanics using numerical solution strategies with computer modeling software. Through the use of modeling software, you will leverage the computational power of the computer to complete calculations that would otherwise be impossible to do by hand. You will also generate clear visual representations of your solution that make interpretation by humans much easier and enable us to develop physical intuition. To ensure that your solutions accurately represent reality, however, you need to first understand how the "black box" of your modeling software functions and have methods to verify and validate your results.
