CFD consultant - Services, consulting & engineering in Computational Fluid Dynamics

Understand physics, and optimise the process.

Computational Fluid Dynamics

NEMOSFLOW is a specialized engineering consultancy in Computational Fluid Dynamics (CFD), based on the passion and expertise of an experienced consultant engineer.

Today, this discipline provides a wide range of answers for understanding, anticipating and optimising any process involving fluids, from purely industrial processes to R&D-oriented projects. Used wisely, a numerical approach can greatly reduce risks and costs, making it a valuable ally in many projects.

The aim of NEMOSFLOW is to share the benefits of this formidable tool, CFD, in a reasoned and sensible way. The offered support covers the entire simulation phase: from the development of the methodology to the analysis and transmission of results, including the construction of the geometric model, the mesh, the physical model and the simulations.

Matthieu Morel - CFD expert and NEMOSFLOW founder

Passionate about fluid mechanics and numerical simulation, I have been working in this field for over ten years and have specialised in it. My career has allowed me to acquire expertise in this field, thanks to multi-sector experiences, firstly as an employee and then as a freelancer. This applies in particular to the sector’s varied and high-quality open source software.

For 4 years, I have been offering this expertise to companies via the single-member company NEMOSFLOW, as a consulting engineer. This status gives me a very beneficial freedom of action and flexibility to carry out the studies in a sustainable, optimized and transparent way. I also have the hope to convey existing interest and benefits in correctly understanding the physics that govern our world and our processes.

Realized CFD projects & simulations

Whether it’s carrying out studies, providing technical assistance or participating in collaborative projects, NEMOSFLOW has been involved in a wide range of sectors. Several major groups and local authorities now call on my services for the following issues:

Thermal simulation

Ventilation and HVAC

Aeraulics in confined and free atmosphere environments

Wind resistance

Multi-phase simulations

Interface monitoring

Atmospheric dispersion


At the end of my assignments, I summarise the issues I’ve tackled and the solutions I’ve come up with in a portfolio of real cases or prototypes based on them. Don’t hesitate to consult it for a more concrete overview of my work!

Publication with Kitware company : scientific visualisation with Paraview

In this blog post, we present some of the many features of Paraview software that are useful for post-processing in Computational Fluid Dynamics (CFD). We illustrate this with a real-life application: the impact of tornado winds on buildings. Read this publication on the Kitware blog.
