To resolve issues in CFD (or Computational Fluid Dynamics it's important to first understand how CFD software works.

In this article, you will be able to understand the basics of CFD and what it is its foundation and the importance of using these advanced methods of simulation to analyze tools for understanding fluid flow behavior and heat transfer processes.

A majority Of CFD software's are broken down into five major phases:

Generator the geometry of our subject matter, Mesh generator, Pre-processor, Processor which obtains the answer, Post-processor.

To be able to analyze every problem that arises to be able to analyze problem CFD the first step is to define your Domain (geometry) and break it into smaller sub-domains (designated by the control volume or element). This is known as a mesh generator (Mesh or Grid).

Pre-processor is a physical simulation that we use to model our flow issue, i.e.: Selecting physical or chemical phenomena that are to be replicated, Definition of fluid properties (viscosity, thermal conductivity, density, etc., Definition of boundary conditions on the outside faces of the mesh.

Boundary conditions are an essential element in the simulation of CFD and should be properly defined since they reflect real conditions and also define the flux and variables within the limits of those conditions.

Post-processors include geometry viewing and mesh viewing, as well as the outputs, which are all based on charts, vector graphics, and graphics on surfaces and visualization of flows and trajectories of particles.
