Nicolas Tardieu, Ing. PhD

Research Interest

I am a research engineer for the french company EDF. My research interests are in finite elements specially when applied to solid mechanics including contact and friction. I also develop preconditioners for fast non-linear solvers.

I have a special interest in scientific software development.

• • I am part of the head of the development team of Code_Aster (an open source finite element solver certified for nuclear safety studies).

  • I also contributed to MEF++  when I was Canada (2004, 2008, 2009)

  • As a lover of Gmsh, I gave a little bit of my time to it
