Nextflow Software, advancing fluid dynamics simulation

Nextflow Software CAE products offer unprecedented CFD simulation capabilities that enable customers across industries to design safer and more competitive products in reduced time and cost

Nextflow Software is an Independent Software Vendor (ISV) startup headquartered in Nantes, France. Nextflow develops and sells advanced Computer-Aided Engineering (CAE) software in the field of Computational Fluid Dynamics (CFD).

Nextflow Software addresses engineering companies developing and manufacturing products and systems involving fluid flows, potentially with complex geometries and interactions with solids (e.g. moving parts, deformations), in the field of automotive, aeronautics, marine, and many other industries.

Thanks to its talented team of researchers and engineers, and based on more than 10 years of close partnership with leading academic research laboratories from Ecole Centrale Nantes (ECN) and other universities, Nextflow Software is pushing the limits of hydrodynamics simulation.


Our mission: advancing fluid dynamics simulation

Nextflow Software aims at becoming a leading contributor to the revolution of computational physics. Nextflow strives to break current numerical simulation limits by integrating leading-edge scientific research into world-class software products. Nextflow products offer unprecedented simulation capabilities that enable customers across industries to design safer and more competitive products in reduced time and cost.

Our vision: developing next-generation CFD software

Nextflow Software provides an innovative and industrial-grade software platform supporting state-of-the-art Computer-Aided Design (CAD) formats. The Nextflow platform allows engineers to perform accurate and quick Computational Fluid Dynamics (CFD) simulations on simplest to most complex systems. The fully-integrated simulation and analysis workflow enables Nextflow users to shorten their engineering cycles and optimize their designs.

At Nextflow Software, we develop innovative algorithms to solve advanced physics, while ensuring ease of use and easy access to simulation parameters, resources and results for all user profiles – beginner to expert. Our products can be used from early concept exploration to final design validation, independently from the complexity of the physics to be simulated.

We address highly nonlinear flows with advanced methods like Smoothed Particles Hydrodynamics (SPH). Compared to other methods, SPH provides better results on very complex and highly dynamic flows, such as tire aquaplaning, gear box oiling, spraying, or in any environment with free surface, liquid film, droplets, bubbles that interact with static or moving solids.

Our flagship solver SPH-flow implements leading edge SPH methods with a volume mesh-free approach and transparent smart surface meshing. Our other solvers implement innovative finite volume method with immersed boundary method, adaptive mesh refinement, etc.

Our integrated workbench provides an intuitive graphical user interface for an optimal user experience covering the complete pre-processing, simulation and post-processing workflow, including the management of computations on High Performance Computation (HPC) environments.

For the marine and offshore market, our dedicated products OptNav, Reva, Aqua+ and ISIS-CFD are available through our partner Tecnitas (formerly HydrOcean, a Bureau Veritas Group company).
