A Memory Efficient Adjoint Method to Enable Billion Parameter Optimization on a Single GPU in Dynamic Problems
Leon Herrmann, Tim Bürchner, László Kudela +1
Dynamic optimization is currently limited by sensitivity computations that require information from full forward and adjoint wave fields. Since the forward and adjoint solutions ar…
Implicit-Explicit Time Integration for the Immersed Wave Equation
Christian Faßbender, Tim Bürchner, Philipp Kopp +2
Immersed boundary methods simplify mesh generation by embedding the domain of interest into an extended domain that is easy to mesh, introducing the challenge of dealing with cells…
Isogeometric Multi-Resolution Full Waveform Inversion based on the Finite Cell Method
Tim Bürchner, Philipp Kopp, Stefan Kollmannsberger +1
Full waveform inversion (FWI) is an iterative identification process that serves to minimize the misfit of model-based simulated and experimentally measured wave field data, with t…
Immersed boundary parametrizations for full waveform inversion
Tim Bürchner, Philipp Kopp, Stefan Kollmannsberger +1
Full Waveform Inversion (FWI) is a successful and well-established inverse method for reconstructing material models from measured wave signals. In the field of seismic exploration…
