CFD simulations

Today’s designers, and engineers, wanting to detect errors at an early stage and make appropriate modifications to the design already can perform computer CFD simulations before production testing begins.

CFD (Computational Fluid Dynamics ) simulations simulations is an engineering tool that uses numerical analysis methods along with data structures to analyze and solve fluid flow issues.

The most common CFD simulations are:

  • fluid flow analysis,
  • temperature transfer,
  • movement of bodies in liquids and gases,
  • predictions of how smoke and heat will spread,
  • wind load analyses, etc.


Advantages of using CFD simulations

Conducting CFD simulations makes it possible to predict the behavior of components in their operating environment. As a result, it is possible to detect errors at an early stage and gain the ability to make design modifications before production testing begins.

Correctly carried out CFD simulation significantly reduces the time of assumption consultation, and dramatically reducing the number of prototypes built, consequently significantly reducing the company’s cost.

For whom are CFD simulations?

CFD is best used in situations where the behavior of the system cannot be calculated using traditional methods. Such situations occur when working on complex projects or buildings that have unusual geometry, for example.

The most common use of CFD simulation assistance is by:

  • mechanical designers
  • building designers
  • architects
  • constructors
  • water and land GIS engineers
  • building and industrial installers
  • safety engineers

What industries use CFD simulations?

CFD is used by many sectors in engineering work to analyze, optimize and verify the performance of designs, thereby significantly reducing the costs associated with earlier prototyping and already proper physical testing.

Examples of industries where such simulations are used:

  • architectural and construction industry
  • civil engineering industry
  • installation industry
  • mechanical engineering
  • automotive industry

What software should I use to perform a CFD simulation?

To perform a CFD simulation, you need a powerful computer and specialized software to perform calculations of free fluid flow and its interaction with surfaces defined by boundary conditions.

One commercial calculation package that includes CFD is Autodesk’s CFD package.

Autodesk CFD is computational fluid dynamics simulation software that engineers and analysts use to intelligently predict the behavior of liquids and gases.

With this software, fast, accurate, and flexible simulations for fluid flow and heat transfer are possible to help predict product performance, optimize designs and verify product behavior before manufacturing.

It significantly reduces the use of costly physical prototypes and brings products to market faster.

Working with Autodesk CFD

The advantage of the software is that it is quite easy to prepare simulations, and it has an excellent mesh generation module that enables precise results while requiring little work in its preparation.

Importantly, the software has a large number of integrated turbulence models that allow the simulation of a variety of phenomena.

Also worth noting is the ability to quickly analyze the results obtained thanks to the Design Center tool.

It helps design engineers make decisions on the subject of flow and thermal analysis, eliminating the costly process of physical testing.

The software is defined as upfront software because it is characterized by its ease of use. It is an easy package to learn and easy to implement and automate simulation processes. Autodesk CFD interacts with a variety of CAD systems from different vendors.
