The aim of the meeting is to bring together applied mathematicians working in the field of numerical analysis and scientific computing, plasma phycicists working on magnetically confined plasmas and fluid mechanicians working on fluid turbulence. The state of the art in the field of numerical simulation of plasma and fluid turbulence will be reviewed and new promizing approaches based on multiscale decompositions will be presented. Numerical methods for Navier-Stokes and Maxwell equations will be discussed, as well as kinetic models based on Vlasov and Boltzmann equations. The interdisciplinarity of the participants will yield synergetic effects and fruitful discussions between the different communities. The attendance is limited to 50 persons and the list of invited speakers is given in the attached file. If you are interested to participate, please send an email, explaining why you would like to come and proposing a title and abstract of the topics you would like to present, to both :
