Computational Fluid Dynamics

What is CFD?

Computational Fluid Dynamics (CFD) is a branch of fluid dynamics that is used to calculate airflow and temperature distribution in a given space. The value of CFD comes from creating a virtual prototype that accurately predicts the behavior of a real system. It allows engineers and managers to gain insight into problems and devise solutions at the lowest possible cost, without having to deploy directly into a production facility.

Is it true that data center CFD models take a long time to solve?

The solve time is dependent on the complexity and the size of the model. We have worked on ways to accelerate solve time, including the use of unstructured mesh and HPC solving using cluster solvers.

The value of CFD cannot be understated. When making critical decisions on your data center power and cooling infrastructure, CFD simulation can provide you with answers that you can make sound decisions on. The trade-off on the solve time is far less impactful compared to making the wrong decision.

CFD models can get out of date very quickly. How do you keep the models up to date?

If you have an existing DCIM solution, we can bring in asset and live data through 6SigmaGateway. This operation is performed in 6SigmaRoom. Additionally, we can also send back temperature and cooling data to your DCIM solution to enhance the planning process. 

If you do not have a DCIM solution, you can use 6SigmaAccess, a browser-based planning software, to update the model. 

Does 6SigmaRoom only work well for design?

6SigmaRoom can be employed across the entire life of the data center—from design to operations. In data center operations, 6SigmaRoom can be used with another DCIM solution or with our planning software 6SigmaAccess.

How much does the software cost?

We have several pricing options to help fit your requirements. You can contact our sales team to request more information. 

What is the payback period for the software?

It depends on the type and scope of the project that the software is used for. Typically, we see that most of our customers start to see return on investment in three to six months. 
The value of simulation is that it can predict the impact of any change you may want to make to a new or existing design. Implementing CFD simulation early in the process can prevent expensive changes in the actual facility down the road. 

Can I deploy your solution on a cloud infrastructure such as AWS, AZURE or GCP?

We mainly provide on-premise solutions that run behind a company’s firewall. However, with our new architecture, we can deploy the central database on the cloud and have our client and server connect to this database. For more details, please contact our sales team.

Can you solve the models on the cloud?

Yes, we have a partnership with Rescale ( that allows you to solve your models using Rescale’s on-demand, powerful hardware.

Can I solve the models on the cluster?

Yes, we have Windows and Linux (LSF) based cluster solver options. 

Is your solution tailor-made for Enterprise Data Centers only?

Our solution’s utility spans across the entire data center supply chain—from designers to operators, including all types of data centers (enterprise, co-lo and hyperscale). Every owner-operator faces space, power and cooling issues regardless of the “type” of data center. 

Is your software web-based?

Yes! 6SigmaAccess is our browser-based, capacity planning software that allows IT hardware planners to make IT changes and pass those changes to the 6SigmaRoom models. To learn more about our operational software, please visit:

How We're Different

We already have a DCIM solution, how can you add value to our current operations?

DCIM solutions are extremely valuable as they address the need to consolidate information, such as assets, tickets and live data, into a single platform. However, DCIM tools lack the ability to model or simulate the behavior of the data center, which is critical for capacity planning. 

How are you different from other Data Center CFD Tools in the market?

Future Facilities’ core technology is built on a CFD engine. However, unlike other companies, we have a suite of products that we have developed for the entire data center supply chain. 

We track all the necessary data, such as temperature and power. Why do we need your solution to help us?

Tracking power and data is important in data center operations. However, monitoring will only tell you what is currently happening in the data center, but not why it is happening. Simulation can identify the root cause of an issue and allow you to plan for the future state of your data center.

We monitor temperature and power; can we bring that data into your model?

Yes, you can easily integrate your data with 6SigmaRoom. Please see our complete list of integrations here

Can I use your software for capacity planning?

Yes. The core idea behind digital twin technology is that it can help predict the outcome of any change. Engineering simulation allows you to forecast layout, power and cooling needs for your facility.
