10 Best CFD Analysis Software for Advanced Product Development (2022)

CFD analysis enables engineers to visualize, test, and analyze their product designs for problems concerning fluid flow, heat transfer, turbulence, non-Newtonian materials, and so on.

The technology has made it easy for organizations and engineers to calculate their design efficiency at any time in any condition virtually. As a result, it saves time, effort, and money.

But the process wasn’t that simple before. Expensive physical testing was the only means to solve practical problems before simulation or CFD analysis came into the picture. It involved rigorous testing using prototypes with lots of recalls and failures.

Apart from testing, you need to fix problems quickly to move the design into production. CFD analysis software helps you with this, and this is what I’m going to talk about in this article.

So, let’s start.

What is CFD?

Computational Fluid Dynamics (CFD) is a part of fluid mechanics that utilizes data structures and numerical calculations to analyze and solve fluid (gases and liquids) flow problems like chemical compositions, density, and velocity.

And the tool to perform CFD analysis and solve fluid flow problems is CFD software. It ensures that the best flow concepts are used from the early stages of product design to enable components to work efficiently under various conditions.

CFD makes it easy to analyze complex fluid flow problems involving liquid-gas, fluid-solid, or fluid-fluid interactions. It uses advanced solvers to transform physical laws from partial differential equations into algebraic equations plus solve them efficiently.

Engineers and analysts use computers to perform these calculations to simulate the freely flowing fluid and its interaction with surfaces. Using sophisticated computers or supercomputers, you can obtain accurate solutions with high speed, even for the most complex issues.

CFD is used in various areas, such as:

  • Aerospace engineering to simulate the aerodynamics of aircraft, turbulent/laminar flow, compressible/incompressible flow, airfoil design, rotating machines, etc.
  • Electronic manufacturing like battery simulation, cooling, and more
  • Heating, ventilation, and air conditioning (HVAC)
  • Automobiles to simulate the aerodynamics of automobile parts, pipe, and valve
  • Prevention cavitation
  • Sports equipment, and much more

How Does CFD Analysis Work?

In general, CFD analysis involves three main phases:

Pre-processing: This is when the fluid flow problem transforms into a discrete and ideal computer model. Engineers and analysts make a few assumptions based on the flow type, such as compressible, incompressible, steady, transient, viscous, non-viscous, etc. They also create a mesh and apply boundary conditions on the interacting surfaces.

Solving: CFD analysis uses powerful solvers that perform actual computations on the fluid flow problems or equations and brings accurate and fast solutions.

Post-processing: Analysts visualize and analyze the results in the final phase to conclude in the form of tables, graphs, moving pictures, etc.

What Are the Benefits of CFD Analysis?

CFD analysis is beneficial in product development in many ways:

#1. Efficiency

#2. More Flexibility

You can measure limited quantities at a time through manual means. However, CFD analysis lets you measure all the physical quantities you want simultaneously with high resolutions due to exceptional computation power. It helps move your design quickly to physical testing and manufacturing.

#3. Practical Feedback

Engineers can create designs and test efficiency before construction with the help of CFD analysis. It allows you to change your model’s shape, structure, size, scale, etc., easily in the software and finalize the most efficient one.

#4. Real-world Experience
