The Laboratoire National de Champs Magnétiques Intenses (LNCMI) is a French large scale facility (LNCMI2013) enabling researchers to perform experiments in the highest possible magnetic field. DC magnetic fields up to 36 T are provided at the Grenoble site and pulsed fields up to 90 T at Toulouse. The technology used for DC magnets relies on the so-called polyhelix inserts for the most stressed parts of the magnets (LNCMI_DCMAGNETS2012). Their design relies on non-linear 3D multi-physic models.

HiFiMagnet is a research project carried out by the (LNCMI) in collaboration with Institut de Recherche Mathématique Avancée (IRMA) and Cemosis.

The goals are twofold:

  1. to build a hierarchy of numerical models ranging from 2D axi to 3D, and including more and more physics. The idea here is to reconsider the hypothesis that are needed to derive the semi-analytical approximations upon which our standard design and optimization procedures are based and ultimately to quantify the hypotheses effects;

  2. to complement our standard design by performing sensitivity analysis and uncertainty quantification on material properties, operational parameters and geometric clearances. It allows e.g. to identify the important parameters, to perform quantile estimation, to compute probability of failure and ultimately to provide safety operational controls.

Models have been implemented with the finite Element Feel++ library

Getting Help

The HiFiMagnet project is developed to help you easily do (i) modelisation simulation and optimisation and (ii) high performance computing. But we can’t do it without your feedback! We encourage you to ask questions and discuss any aspects of the project on the discussion list or in the chat room.
