Siemens buys Nextflow to speed simulations with advanced meshless tech

Siemens reports it has acquired Nextflow Software, an independent provider of advanced particle-based computational fluid dynamics (CFD) solutions. Nextflow Software will become part of Siemens Digital Industries Software. The transaction closed on June 1, 2021 and terms have not been disclosed.

Its offering will expand the Simcentre software portfolio, part of the Siemens’ Xcelerator portfolio of software and services, with rapid meshless CFD capabilities to accelerate the analysis of complex transient applications in the automotive, aerospace, and marine industries such as gear box lubrication, tank sloshing or electric motor spray cooling.

“Our customers need to leverage sophisticated simulations earlier and more often in their design process, and this is creating a strong demand for rapid and automated CFD of dynamic gas-liquid flows,” says Jean-Claude Ercolanelli, SVP, simulation and test solutions, Siemens Digital Industries Software.

“Meshless technology has emerged as a solution to greatly reduce the setup and solving times for this class of problems, accelerating time to results and prove the behaviour of products at a reduced time and cost.”

Siemens Digital Industries Software is already positioned strongly in the CFD market, providing both CAD-centric and high-fidelity solutions across mechanical and electrical design scenarios.

The addition of Nextflow Software’s Smooth-Particle Hydrodynamics (SPH) technology into the Simcentre portfolio can enable analysts to leverage the complementary nature of meshless and mesh-based solvers to capitalise on each of their strengths, opening the door to new applications that were previously difficult to address.

“We are very excited to join Siemens and expand the scope of CFD simulation for our customers,” says, Vincent Perrier, CEO of Nextflow Software “There is no single validation approach that fits all industrial applications.

As engineering problems become more complex and design cycles are shortened, analysts must find the optimal trade-off between accuracy and computation time. Nextflow Software’s SPH solutions nicely complement the existing CFD offering in the Simcentre Portfolio to overcome challenges of complexity and long run-times.”

Founded in 2015 and headquartered in Nantes, France, Nextflow Software is a startup company focused on the development of innovative SPH meshless CFD methods. They have played a critical role in moving SPH from academic labs into the hands of analysts across industries, helping simulate complex transient problems faster and earlier in the product development cycle.
