Engineering solutions for the 21st century's increasingly complex challenges

In the last 30 years there has been an extraordinary increase in simulation and modeling tools used by design engineers, decision makers and public services.

Research in mechanical and process engineering has provided a significant contribution to progress in these areas.


Today's scientific and technological challenges arise from new issues:

sustainable development, alternative resource management, green technologies, environmental impact, risk management, health care...

The aim of Tec 21 Laboratory of Excellence is that our research contributes to developing new engineering solutions for today’s increasingly complex challenges through

  • gathering new knowledge and understanding, developing new concepts and methods, and improving measurement as well as simulation capabilities...
  • giving rise to educational multidisciplinary programs providing practical experience. 
  • working towards solutions having direct industrial and environmental applications.

Grain of snow, or no grain of snow?

By coupling experimental observations and mechanical modelling, the researchers from IRSTEA Grenoble have developed a new computational method to simplify the identification of individual snow grains in the complex network of ice crystals that makes up the snow (read more).

Image caption: 3D image of a snow sample (1 cm3). The bonds between snow grains were defined using either the method of mechanical stress computation (black rings) or the new algorithm based on geometrical clues (pink zones).
