CFD(Computational Fluid Dynamics) refers to a set of computational simulation techniques that are used to find and interpret computational solutions for conservation equations for physical substances that are important in a flow. which are:
1. Mass conservation
2. Momentum and energy conservation
These simulation techniques predict physical and/or chemical phenomena occurring in inflows. A Fluid Simulation (”fluid sim”) is a special toolset that helps to mimic the effect of fluids in an environment. You can browse www.simulacionesyproyectos.com/ to know more about fluid simulation.

They will simulate the physical phenomena in an approximate way to the differential equations. Those differences refer to errors or residuals.
To solve problems in CFD, it's necessary to specify the problem, i.e. its geometry, flow conditions, and the requirements for simulation.
And what's the CFD importance?
In CFD it's possible to model and evaluate the fluid flow performance in our study model. The application of CFD simulation offers a set of advantages when compared to theoretical and experimental studies:
1. Purchase and operation low cost
2. Detailed information about the fluid flow studied
3. Allows the quick change of parameters in the flow analysis
Despite all, the CFD does not substitute theory and experience; we should always approach two, to interpret the results. The comparison with experience gives us the accuracy achieved by the simulation.
Post-processor includes geometry viewing and mesh viewing, and all results using vector graphics, charts, graphics on surfaces, and visualization of flow lines and trajectories of particles.
