What is CFD?
CFD is the simulation of fluids engineering systems using modeling (mathematical physical problem formulation) and numerical methods (discretization methods, solvers, numerical parameters, and grid generations, etc.)
Historically only Analytical Fluid Dynamics (AFD) and Experimental Fluid Dynamics (EFD).
CFD made possible by the advent of digital computer and advancing with improvements of computer
