What is Computational Fluid Dynamics (CFD)?
Computational fluid dynamics is an engineering analysis method used to understand how fluids flow in or around an object [1]. CFD analysis uses theoretical fluid dynamics models obtained from the Navier-Stokes equation to simulate how a specific fluid will flow around an object [1]. Other CFD software use the Lattice Boltzmann Method to solve CFD simulations [2]. By doing CFD analysis on a part you can drastically reduce the amount of prototypes and lower the development cost of the final product [1]. CFD has many applications as it can be used for anything that involves a fluid in motion. CFD can be used to simulate incompressible flow, compressible flow, laminar flow, turbulent flow, mass transport, and thermal transport [2]. The most common applications of CFD are HVAC, aerodynamics, heat transfer, turbomachinery, high-performance computing (HPC), electronics cooling, cleanrooms, and pipes and valves [2].

Computational Fluid Dynamics Software
The following 6 most popular CFD software are the top 5 best rated CFD software and the more accessible software to students [3].
ANSYS
ANSYS is the highest rated CFD software [3].
OpenFOAM
dfbdf
PowerFLOW
defb
SimScale

from highest to lowest popularity are ANSYS, OpenFOAM, PowerFLOW, SimScale, COMSOL Multiphysics, and Autodesk CFD [3]. The most accessible cfd software for University of Waterloo students is flow simulation in SOLIDWORKS. For projects that require a high degree of accuracy, it would be best to use a dedicated CFD software such as ANSYS over flow simulation in SOLIDWORKS.
CFD in SOLIDWORKS
cavitation, wizard, fix computational domain for faster computing, then regions you want, added goals of whats recorded, run, expand and view results, flow trajectories are flow points (lines)
