New features:

  • added acoustic forward modelling/FWI/RTM module
  • added time integration FWI as suggested by Linbin Zhang
  • added visco-elastic SH forward modelling/FWI module according to Fabien-Ouellet et al. (2017)
  • normalized parameter classes, parameter scaling and diagonal Pseudo-Hessian approximaton for
    the visco-elastic SH FWI problem
  • added MODE=3 to compute FD-based gradients for the visco-elastic SH case
  • options to suppress model and STF output
  • Improved Vaccuum Formulation (IVF) by Zeng et al. (2012) and Pan et al. (2018) for accurate
    modelling of surface waves in the presence of complex topography
  • anisotropic Gaussian filter with coherence length adapted to the local S-wave wavelength to impose
    smoothness constraints on gradients
  • 2-level parallelization for the PSV module based on domain decomposition and shot parallelization
    by Vladimir Kazei
  • Replace data type of objective function from float -> double

The visco-elastic SH FWI is still "work in progress" and shows some significant convergence problems. Therefore, I currently recommend to use the old DENISE-SH code:

for field data applications.
