Siemens announced on June 9 that it has acquired Nextflow Software, a provider of solutions for particle-based fluid dynamics (CFD) simulations. Nextflow Software becomes part of Siemens Digital Industries Software and expands the Simcenter software portfolio.

According to the press release, the software brings fast mesh-free CFD capabilities that accelerate the analysis of complex transient applications. In the automotive, aerospace and marine industries, these include applications such as lubrication of gearboxes, tank sloshing (movement of free fluid surfaces during sloshing processes) and spray cooling of electric motors.

Jean-Claude Ercolanelli, senior vice president, Simulation and Test Solutions, Siemens Digital Industries Software, is quoted as saying, “Our customers need to be able to perform sophisticated simulations more frequently and earlier in the design process, and thus the demand for fast and automated CFD simulations for fluid dynamics in gases and liquids is growing strongly.”

With the integration of Nextflow Software’s Smoothed-Particle Hydrodynamics (SPH) technology into the Simcenter portfolio, analysts can now leverage mesh-free and mesh-based solution approaches.

Nextflow Software was founded in 2015 as a startup and is headquartered in Nantes, France. The transaction closed on June 1, 2021. The press release does not provide information about the purchase price or the terms of the agreement.
