Next-generation CFD software

We have interviewed Matthieu de Leffe, CFD R&D Director at Nextflow Software. By watching this 2:30 minutes video testimony, you will discover Nextflow Software scientific fundamentals.

“Scientific fundamentals, at Nextflow Software, are developed with our academic partners, which are the LHEEA, from Ecole Centrale de Nantes (France) and CNR-INM institute in Rome (Italy). So to model fluid flows, we use mathematical equations, which are the Navier-Stokes equations for fluids. These equations are resolved by our software.”

We have interviewed Laurent Dionisi, Software engineering manager & project manager in agile methods at Nextflow Software. By watching this 2 minutes video testimony, you will understand the missions of Laurent Dionisi’s department.

“My department has 2 main missions:

• the first one is to provision all IT tools: compiler, configuration management tool, continuous integration farm, automatic tests, etc.
• the second mission is the development of satellite products to the solvers, especially the Studio product, which is our graphical interface and allowing to prepare the simulations, to monitor them and to check with post-processing if the computations went well. “

Laura Trappolini, product manager at Nextflow Software, shares her product and technology vision. We interviewed her a few days ago to understand better her job and missions. Discover her video testimony right now (2,30 minutes).

• “Usually, in other CFD companies, we develop only mesh-based solutions. In Nextflow, we made the decision to develop meshless solutions […] The engineers can rather focus on the physics rather than on the meshing process.”
• “So in Nextflow, we have commercialized a first solver called SPH-flow. […] In this solver, we can represent accurately highly dynamic fluid flow with the free surface and also complex body motion.”

We have interviewed David Le Touzé, Deputy Director of LHEEA Lab (ECN and CNRS), as part of our strong partnership with Ecole Centrale de Nantes.
By watching David Le Touzé video testimony (3 minutes), you will discover our genesis and the SPH method evolution.

“We started to work on the SPH method about 20 years ago. At the time, it was very difficult to model with a conventional CFD complex air-water interface. It was also very difficult to have in fluid dynamics simulation multiple bodies or multiple objects which we were moving together. The SPH method was quite attractive because it actually permitted to do these things quite straightforwardly, but of course it was a very young method, so we had to do lots of academic developments.”
