Studies, consultancy and calculation services in fluid mechanics

Matching our offer to your needs. Applying our know-how to your problem.

Your project doesn’t always require complex numerical modelling. Sometimes, all we need to do is provide you with a few elements of our expertise in Fluid Mechanics to help you turn your project into a success.

That’s why we offer a wide range of services, including literature reviews, analytical studies, calculation services and technical advice tailored to your needs.

The results are delivered to you in a variety of formats: summary report, PowerPoint presentation, Excel spreadsheet, simplified programme automating the calculation.

This service will enable you to effectively integrate OptiFluides’ expertise into your projects in a targeted field, thanks to deliverables tailored to your immediate needs and designed for direct implementation. It can also be carried out in parallel with one or more more comprehensive modelling studies. These simulations could, for example, be used to determine the parameters of a simplified head loss or flow rate law, which would form the deliverable of the study.

Some examples of possible support

  • Calculation sheets for thermal analysis of buildings
  • Technical report counter-expertise
  • On-site equipment audit
  • Advice on the design of industrial equipment (e.g. mixers in process engineering)

Experimental measurements in fluid mechanics

Genuine added value to numerical simulation

Numerical modelling generally requires a good knowledge of the physical quantities of the system at stake:

  • An initial state, to accurately adjust the numerical model and calculate other states of the system.
  • A similar system, to determine the influence of a geometric or functional change, etc.
  • At the limits of the system, to provide keys for validating the results or parameterising the model accurately.

Numerical modelling of a system alone is sometimes not enough, which is why OptiFluides can strengthen its guarantees on the consistency of numerical results by offering a wide range of tests and experimental validation on models or test benches.

CFD numerical simulation

CFD modelling, our core expertise

Our company has always chosen to focus exclusively on Fluid Mechanics and the numerical simulation of flows. This is not an innocuous decision: this is a highly technical field, the perfect mastery of which is undeniably correlated with constant practical application.

Over the last 15 years, we have become experts in the numerical modelling of all types of flows:

  • laminar or turbulent,
  • stationary or unsteady,
  • single-phase or multiphase,
  • with phase change, heat exchange, combustion, etc.

We put our expertise in CFD numerical simulation at your disposal, both for your R&D projects and for industrial studies.

Modelling computing power

HPC cluster
OptiFluides has an HPC2 cluster with more than 1,000 parallel computing cores. All our processors communicate via an Infiniband bus, which is now one of the fastest network exchange standards.

Workstations
To complete its hardware installation, OptiFluides has invested in the latest Dell and HP workstations. Each has up to 16 hyper-threaded cores and 50 gigabytes of RAM.

Computing centres
For simulations requiring even greater computing power, OptiFluides has signed agreements with a number of supercomputer computing centres, including :

  • P2CHPD3 – Pôle de Compétence en Calcul Haute Performance Dédié.
  • CINES4 – Centre Informatique National de l’Enseignement Supérieur.
  • IDRIS5 – Institut du Développement et des Ressources en Informatique Scientifique.

2. An HPC or High-Performance Computing cluster is made up of a group of networked computing servers that will appear as a single computer with greater capacity, which adds considerable value to the digital process.
3. P2CHPD is the HPC computing centre located at La Doua, Villeurbanne, FRANCE, which is part of the federative structure ‘Fédération Lyonnaise de Calcul Haute Performances’ FLCHP, the HPC meso-computing centre for the Lyon region.
4. C.I.N.E.S. (Centre Informatique National de l’Enseignement Supérieur) is a national public institution, based in Montpellier (France) and placed under the supervision of the Ministry of Higher Education and Research.
5. IDRIS (Institut du Développement et des Ressources en Informatique Scientifique), founded in November 1993, is the CNRS’s major centre for very high-performance intensive digital computing.
3,4,5. These computing centres are available to us in partnership with M. Buffat, L. Le Penven and A. Cadiou of the Laboratoire de Mécanique des Fluides et d’Acoustique (a joint research unit attached to the CNRS, Ecole Centrale de Lyon, Université Claude Bernard Lyon 1 and INSA Lyon).

Data security

We take the protection of personal data very seriously. We systematically inform you when a user accesses and/or modifies your data. If you have entrusted us with personal computer data, you can request information about the data stored at any time. You also have the right to have this personal data deleted.
In addition, we insist on protection measures to block any intrusion on our servers.

CFD and fluid mechanics training

From familiarisation to expertise

OptiFluides offers training courses tailored to your business in order to introduce you to the fundamental concepts and give you a glimpse of the limits and challenges of Fluid Mechanics modelling.

To meet your needs perfectly, this type of training – always tailor-made – ranges from an introduction to numerical simulation to in-depth, specialised training in CFD applications in one of our business sectors.
