CFD stands for Computational Fluid Dynamics, which is an engineering tool included in what is generally known as Computer Assisted Engineering (CAE). Specifically, CFD refers to the simulation of the fluid flow, considering the physical and chemical phenomena involved (such as turbulence, heat transfer or chemical reaction).


What can CFD bring to my company?

Through the simulation you can improve the design of a process or product without spending lots of time and money in building prototypes; you can avoid making wrong decisions; you can acquire a better know-how of the process or product, which will allow you to faster improve your design processes, as well as to solve problems in existing systems.

How can I add the CFD to my company?

We offer different options which adapt to the needs of each client. In the case of occasional needs, nablaDot executes the CFD project, providing the client with the required results. On the other hand, if a regular use of CFD services are foreseen and you want to internalize the process or product know-how, nablaDot can customize CFD software according to your needs and computational resources, training your staff in its use.

What does a CFD project implies?

Essentially, a fluid simulation project entails a previous study of the process/phenomenon to analyze, a detailed geometric model, the choice (and implementation when required) of the proper mathematical models, the aplication of the operation data as boundary conditions, the numerical calculation (which may vary from minutes to days, depending on the complexity of the models) and the result analysis. Thus, despite the development of applications to ease the use of these tools in the past years, in order to properly execute a CFD project requires a significant expertise and resource investment.

How much does CFD cost?

CFD is not the cheapest engineering tool (compared to the costs of a spreadsheet or a standard CAD tool) because of its complexity and requirements (expertise, licenses and computational resources). On the other hand, the results obtained and its contribution to the design process or problem resolution are significantly superior to those obtained with simpler tools.

The time reduction in the design, the savings regarding the prototype building and the improvements in the process or product usually make up for the CFD cost. Besides, there are some ways to reduce the cost of this sort of projects:

  1. 1. The projects involving fluid simulation or CFD implementation in a company can be considered as R&D projects, which may benefit from tax deductions.
  2. 2. Adding CFD tools to the company cycles is considered as an action towards the transformation to industry 4.0. Nowadays, and probably in the near future, public administration is financing this sort of actions, which may be used to execute this kind of projects.
  3. 3. This sort of projects can be included in R&D projects with public financing, such as H2020, CDTI or national/local calls.
