CALVI Research team

Activity reports

Introduction

CALVI was created in June 2003.

It is a project that initially associates Institut Elie Cartan de Lorraine (IECL, UMR 7502, CNRS, Inria and Université de Lorraine), Institut de Recherche Mathématique Avancée (IRMA, UMR 7501, CNRS and Université de Strasbourg) and Laboratoire des Sciences de l'Image, de l'Informatique et de la Télédétection (LSIIT, UMR 7005, CNRS and Université de Strasbourg) with close collaboration to Laboratoire de Physique des Milieux Ionisés et Applications (LPMIA, UMR 7040, CNRS and Université de Lorraine).

Our main working topic is modelling, numerical simulation and visualization of phenomena coming from plasma physics and beam physics. Our applications are characterized in particular by their large size, the existence of multiple time and space scales, and their complexity.

Different approaches are used to tackle these problems. On the one hand, we try and implement modern computing techniques like parallel computing and grid computing looking for appropriate methods and algorithms adapted to large scale problems. On the other hand we are looking for reduced models to decrease the size of the problems in some specific situations. Another major aspect of our research is to develop numerical methods enabling us to optimize the needed computing cost thanks to adaptive mesh refinement or model choice. The visualization topics were discontinued after the departure of one of our collaborator.

The CALVI project ended on December 2013. The main research subjects developed in CALVI will be continued through the new project TONUS, which started in January 2014.
