DIVA-DG

Participants : Lionel Boillot, Marie Bonnasse-Gahot, Théophile Chaumont-Frelet, Jérôme Luquel.

DIVA-DG is the simulation code that we develop in collaboration with our partner Total. This year we have implemented

• 2D/3D anisotropic elastic Absorbing Boundary Conditions for time-domain.

• 2D elastic imaging conditions.

• 2D multiscale strategy to take into account fine scale heterogeneities on coarse meshes in frequency domain.

• Hybrydized Discontinuous Galekin method for 2D elastodynamic in frequency domain.
