**Computational Fluid Dynamics**

The prediction of the behaviour of fluids and of the effects of fluid motion past objects by numerical methods rather than model experiments

**Finite Element Analysis**

The finite element method (FEM) (sometimes referred to as finite element analysis (FEA)) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The solution approach is based either on eliminating the differential equation completely (steady state problems), or rendering the PDE into an approximating system of ordinary differential equations, which are then numerically integrated using standard techniques such as Euler's method, Runge-Kutta, etc.
