What is CFD?

The fluid problem complexity arises from the nature of it’s governing equation, the Navier-stokes equations, which are non-linear partial differential equations. These equations are super hard and even impossible to solve using the analytical method and mathematically not yet fully understood, the price of $1.000.000 is prepared for those who solve these equations “smoothly” (read millennium prize).

Unlike well-understood problems, Instead of solving it’s governing equations, engineers and scientists prefer to solve the fluid mechanic problems using experimental methods in the lab, or using a numerical method to “estimates” the solution. The later is called Computational Fluid Dynamics (CFD).

Using CFD method, engineers or scientists are able to solve or predict the fluid flow-related problems such as studying the basic flow characteristics, design optimation, design assessment, failure investigation, proofing novel ideas, design comparison, and many others tasks in more flexible, fast, economically and deeply compared to lab experimental study or risky field-test.

What is velocity consulting?

Although CFD modeling is an advanced method, this tool will not generate proper results in the wrong hand. We are here to become the solution to your company or research to conduct such CFD simulation right exactly what you need at a proper price.

Our team has been experienced with CFD simulation for years, ranging from detailed mathematical and numerical modeling for scientific research to industrial in-field problems in many industries, such as energy, HVAC, aerospace, process, construction, urban planning, marine, automotive, and proofing novel ideas.

To provide the best solution that suits your budget, we used opensource software, openFOAM, so your wallet is not burdened with unneeded high software licensing price and we can tailor dedicated-solver based on your need. But, if your company already has licensed commercial CFD software, please let us know.

openFOAM software

OpenFOAM is the free, open-source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organizations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics (
