Bilateral Contracts with Industry

Nucletudes

Participants : Patrick Breuilh [Nuclétudes, Les Ulis, France] , Alexis Gobé, Stéphane Lanteri.

The objective of this collaboration with the Nucletudes company that has been initiated this year is to design a high order HDG formulation able to deal with non-conforming hybrid cubic/tetrahedral meshes, for the simulation of time-domain electromagnetic wave propagation problems with applications to radiation hardening. This first part of this study has been concerned with the specification and development of a preprocessing tool for the construction of such hybrid structured/unstructured meshes.
