Is there a significant difference between the two and what each one used in the first place?

The basic idea behind it is part of the "minor differences", an attribute value in a particular location, ie a value that have very different than in the right place at his side.
On this basis, and the presence of boundary conditions (for CFD is the physical presence of the moving object, while the liquid and the wide range of free conditions, while for finite element, which change the nature of the hand, the edge of one hand may be a change in thickness, and so on), a division of property of the computer when an iterative process of relaxation.
CFD is working primarily on the aerodynamic design contours of aircraft and cars, and determine the stability properties. Finite elements for the design of mechanical parts under stress, employed to help define how thick to make to each section of components and parts, and predict the most likely to occur when the error, and it is so common in the aerospace and automotive industries, but also at any other place where something has to bear the burden of varying-scale and which do not allow for reasons of cost or weight of a brute force design concept.
Now CFD calculation means in accordance with a method, although the sea is a method. Typivally fluid mechanics to flow continuously and continuous functions and differences of these functions. Finite element analysis can imagine, with a grid of points separated by a finite distance of each other (regardless of the limit as the separation goes to zero, as (in the df / dx = limit h -> 0) [f ( x + h) - f (x)] / h, the differential analysis is typical), then the points in the network with a range of values for the parameters that are relevant, and a series of calculations, given the current configuration an overall improvement, usually in a moment, a small step forward to calculate.
The finite element analysis can be used with more frequency in the static, like a bridge (or other structure) to examine and calculate the forces on a network share points of a finite number of simple elements.
Mechanics of Fluids most often is that the calculation of fluid motion by several factors.
