Logo Meteodyn CLS white


Founded in 2003 by Dr. Didier DELAUNAY, worldwide recognized expert in wind engineering, Meteodyn has rapidly developed and is now operating internationally.
Currently, Meteodyn is present in The United States, France, China and India. Additionally, products are also available worldwide through multiple resellers.

CFD wind modeling software and dedicated consulting services

At Meteodyn we develop CFD* software that can model the wind on any terrain, even complex. We also perform climatological studies as well as micro-meteorological studies.

Our products and services integrate the best wind engineering dedicated to renewable energies, urban planning and wind safety in transport and infrastructures.

Our software facilitates the estimation of the wind resource, the analysis of wind characteristics and the analysis of urban microclimates. We also offer a wind power forecast service using artificial intelligence, as well as consulting services for the wind safety of buildings, trains, cars, tower cranes, and bridges. We are also developing custom real time wind mapping applications dedicated to ports.
Today, we are pleased to say that our technical expertise is recognized internationally. 

*CFD: Computational fluid dynamics


We are committed to being at the forefront of technology and innovation.

We collaborate with our customers to ensure we always meet their requirements. We also work with them to develop the software features they require.

The quality of our software and our technical expertise is the result of a strong collaboration and synergy between our teams.

Research experts, engineers, computer programmers and account managers work together to create software combining CFD technology, climate engineering, accuracy and usability.


partnership research programs
we have worked on

swip project

The SWIP program

From October 2013 to October 2017

The SWIP project (New innovative solutions, components and tools for the integration of wind energy in urban and peri-urban areas) seeks to develop the European market for small wind turbines.

Small wind turbines remain an underutilized technology, despite its potential, due to various obstacles opposing their emergence (cost, efficiency, noise, safety, aesthetics, etc.).

SWIP's goal is to develop and test innovative solutions to overcome this reluctance, reduce maintenance costs and improve performance. The project team is working on a new wind potential assessment methodology, a low-cost generator, a new blade design and a SCADA monitoring and control system to improve operation and maintenance tasks.

The SWIP project is co-financed by the European Commission and its coordination is ensured by the CIRCE Foundation.

Hyperwind project

The HYPERWIND program

From November 2013 to March 2019

The HYPERWIND project consists in developing a global monitoring system for offshore and onshore wind turbines. 

Hyperwind seeks the following:

  1. Provide a hyper-control system for offshore wind farms,
  2. Provide a global and systemic monitoring system of all wind turbine components,
  3. Provide a remote monitoring system that is reliable and easy to interpret,
  4. Develop a methodology for constructing models and indicators for use on different machines,
  5. Present a prototype on a powered onshore wind turbine,
  6. Offer integrated structural health monitoring solutions for future wind farm projects.

The partners: KEOPS Automation, Net-Wind, Airbus and Meteodyn, the Ecole des Mines de Nantes and the Mer Bretagne Atlantique cluster.

The project, labeled by the EMC2 cluster, is financed by the Fonds Unique Interministériel and the Pays de la Loire Regional Council.

envie program

The ENVIE program

From January 2011 to July 2013

The ENVIE project (Enrichment of Digital 3D Cities by Sustainability and Environmental Quality Indicators) is financed by the FEDER and OSEO.

The aim is to create 3D models of cities to gather complementary information and to provide it to public actors so that they have more information to make decisions. 

Here are the partners of this project and their roles:

  • SIRADEL provides 3D city models and heat loss maps. It compiles all eco-indicators on a final model.
  • Meteodyn produces quantitative eco-indicators (solar gain, wind resource) and qualitative eco-indicators (pedestrian climate comfort).
  • MGDIS brings its knowledge of national databases (INSEE, SIRENE, cadastral database) to feed the models with economic and social information.
  • CERMA, a research laboratory of the Nantes National School of Architecture, analyzes lighting and urban environments.
ISERE program 2

The ISERE program

From June 2008 to February 2011
The ISERE project, "Integrating Atmospheric Stability into Wind Resource Assessment" was financed by the ADEME and carried out in partnership with Maïa Eolis.

It focused on the automatic integration of atmospheric stability into wind energy production calculations.

IRCAD program

The IRCAD program

From December 2004 to January 2009
This program, funded by the French Ministry of Transport, included INRETS, LCPC, the General Council of Côtes d'Armor and Meteodyn.

This research has improved traffic information in degraded weather conditions.


The WEATHER program

From October 2004 to June 2007

The WEATHER program has developed methodologies for the analysis of risks due to crosswinds on road or railways. The research focused on vehicle aerodynamics, wind modeling, very short wind forecasting, risk analysis and wind warning systems. Read the presentation of the program.
