We are thrilled to announce the addition of Edouard Lété as VP sales. His role will be instrumental in driving momentum and growth for Nextflow Software.

Edouard was previously the CEO of Digital Orthopaedics, a company developing digital twin of personalized organs. He has also worked 15 years for SIMULIA, a Dassault Systèmes brand, at several senior management positions.

We recently interviewed Edouard Lété. We asked him how his career got started in engineering simulation and why he chooses to join Nextflow Software. Discover his vision in this article!

How did you first become involved with engineering simulation?

I first came across structural simulation while studying for my mechanical engineering degree. During graduating, I have been working for my master’s thesis on design and analysis of leaf springs & rims, a work sponsored by Volvo Trucks. Then, I was hired by them to deploy my work and start the stress department of the special truck division in Ghent. My passion for numerical simulation starts at that time and it has never stopped until today.

Why expanding the use of simulation technologies is important?

“From the start, it has been a constant focus for me to make realistic simulation accessible to a wider audience and in new domains where product testing remains the only proof of truth. The healthcare domain is a good example.

With the evolution of HPC, the advances in the integration of processes, the easy & cheap access to public HPC clusters, it becomes a reality for many application domains. The access to complex simulations without compromising with the accuracy is now possible to any company, even small. It is critical as the democratization of the simulation also means removing many barriers to sustainable innovation.”

You are now selling the CFD solution developed by Nextflow Software, why?

Many advances have already happened in structural analysis with the CAD integration for product design and validation. CFD is still behind in democratization, as there is not always a CAD design (dam, river or human body). There is also a need for discretizing the environment which requires skills and meshing expertise, still a barrier to simulation for traditional CFD solutions. With the products developed by Nextflow Software, we are removing these barriers and therefore, it opens the door to many other applications still not addressed. I am excited to join this team.

What do you see as the most important benefits of SPH-flow ?

The SPH methods (Smoothed-Particle Hydrodynamics) used in SPH-flow, the main product of Nextflow Software, are meshless methods or also called particle-based methods. It does not require to mesh the environment and does not necessary require to have the CAD model of the product to be studied.

The software is also coupled to extend the reach of the traditional structural or CFD analysis solutions. It also removes the barriers between structural and fluid mechanics engineers as both can have a need of such product. We can say that any mechanical engineer can use the software with just some training.

Can you share with us an example of a benefit from an industrial application case?

“For example, the A2MAC1, a benchmaking company in the automotive, is a very good example.

Based on the scan of a car (they have 600 models in their catalog), they can study and compare performance of cars during water fording thanks to SPH-flow. No need to generate a complex mesh of the fluid around the car and even no need of CAD model in such case! Integrating such process, we can even fully automate it.

What are some of the challenges that you have also witnessed?

“These methods can not cover the entire scope of the CFD applications area. None of the technologies in place can do it anyway. We believe that about 20% of them could be replaced by this technology. Moreover, these methods can extend the application area of the CFD and structural domains.
The meshless methods and especially the SPH
method have already demonstrated their accuracy since the last 10 years. We still need to initiate a discussion and potentially convince some CFD specialists that only rely on traditional methods such as finite volume methods so far. The first challenge we face is certainly to turn minds from a traditional approach.

What does Nextflow Software provide to help industry overcome these hurdles?

“We support the entire product development process, and the different actors of this process- from the first idea to the final validation of the product. We are developing and presenting many use cases to demonstrate the wide scope of such methods, create ideas and open minds.
In the near term, the ambition of Nextflow software is to provide a platform with a suite of solutions. Users will be able to choose the best method between “accuracy” and “speed” in the incompressible or compressible fluid domains. The platform will allow to shift from one approach to the other one without effort.

Are there any other closing comments you would like to share with us?

“Democratization without compromising with the accuracy is key to the success in the numerical simulation. Innovation is not coming from the technology itself but the way such technology will be used by our customers. I strongly believe that Nextflow Software solutions are key enablers for sustainable innovation. With my team, we will demonstrate that value! “
