3、es this picture help explain it?Predicting aerodynamics(or aerothermodynamics or acoustics)at a single flight condition means solving forstate variables at millions of pointsAnd the points are highly interrelated,so you cant solve one at a time7How Does it Work?Split the flow into smaller chunksEach
