Poster: Multi-Level Iterative Reconstruction with Elastic Surface and Body Waves on Unstructured Tetrahedral Meshes

Sign up or log in to save this to your schedule and see who's attending!

Feedback form is now closed.
We model the elastic time-harmonic waves using
the continuous Galerkin (CG) finite element method on unstructured tetrahedral meshes
and study the elastic full-waveform inversion with surface and body waves.
We project the scaled gradients onto stable subspaces
and further a multi-level scheme to stabilize our iterative reconstruction.
The procedure is illustrated via several computational experiments.
