What is Computational Fluid Dynamics or CFD Discretization?
The word discrete is opposed to the concept of continuity. While at the Quantum level, things are explained with concepts like quantas, discrete packets, etc., in classical physics, continuity holds in describing mathematical formulations and also their solutions. Discretization concerns the process of transferring continuous models and equations into discrete counterparts. This process is usually carried out as a first step toward making them suitable for numerical evaluation and implementation on digital computers. Discretization can be performed on several continuous entities like, images, equations, geometries, features, etc. In the context of CFD, discretization is performed to solve the Navier-Stokes equations whose direct solution would otherwise be extremely difficult and in most cases impossible. The solution process may involve the usage of digital computers. Discretization in any CAE analysis involves breaking-down of the given geometry where the computation has to be perfor
