Seismic Waveform Modeling

  • FDFDMATRIX3D: Solution of the 3D time-harmonic visco-acoustic VTI wave equation with the 27-point finite-difference stencil.
  • SEMLAB: Spectral Element Method for wave propagation and rupture dynamics in Matlab.
  • SEISMIC_CPML: a set of sixteen open-source Fortran90 programs to solve the two-dimensional or three-dimensional isotropic or anisotropic elastic, viscoelastic or poroelastic wave equation using a finite-difference method with Convolutional or Auxiliary Perfectly Matched Layer (C-PML or ADE-PML) conditions
  • SPECFEM2D: SPECFEM2D allows users to perform 2D and 2.5D (i.e., axisymmetric) simulations of acoustic, elastic, viscoelastic, and poroelastic seismic wave propagation. The package can also be used for full waveform imaging (FWI) or adjoint tomography.

  • SW4: SW4 (Seismic Waves, 4th order) implements substantial capabilities for 3-D seismic modeling, with a free surface condition on the top boundary, absorbing super-grid conditions on the far-field boundaries, and an arbitrary number of point force and/or point moment tensor source terms.
  • SALVUS: Salvus is a suite of software for performing full waveform modelling and inversion provided by Mondaic.
  • Devito: Code generation framework for automated finite difference computation
  • FDwave3D: A Matlab solver for the 3D anisotropic wave equation using the finite-difference (FD) method.
