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

Securing decisions, understanding physics, and optimizing processes

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 rational and reasonable manner, in order to:

  • Secure technical, regulatory, or design decisions;
  • Provide a well-founded and solid opinion based on digital engineering;
  • Reduce the risks and costs associated with a project;
  • Understand the physics involved in order to optimize a process.

The support offered is comprehensive and personalized:

  • Analysis of the problem at hand;
  • Review of physical assumptions and digital strategy;
  • Development of methodology, modeling, and simulations;
  • Identification of major risks and quantification of uncertainties;
  • Clear recommendations.

Matthieu Morel - CFD expert and NEMOSFLOW founder

Passionate about fluid mechanics and numerical simulation, I have been working in this field for over 13 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 6 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.

Some testimonials
