The seismic working group develops 2-D and 3-D time domain finite-difference numerical methods which are applicable to arbitrary complex media. Domain decomposition by using MPI allows to use modern cluster technology.
SOFI2D, SOFI3D and SOFI2D_sh are published and distributed on a gitlab server located at the KIT. The following links lead to the latest releases:

Full waveform inversion (FWI) is a cutting-edge inverse method that accounts for the full seismic waveform recorded over a broad range of frequencies and apertures. It iteratively retrieves multiparameter models of the subsurface by solving the full wave equation. It furher allows for a mapping of structures on spatial scales down to less than the seismic wavelength, hence providing a tremendous improvement of resolution compared to traveltime based methods.
