Quoted from: https://geodynamics.org/cig/software/specfem2d/ 

SPECFEM2D simulates forward and adjoint seismic wave propagation in two-dimensional acoustic, (an)elastic, poroelastic or coupled acoustic-(an)elastic-poroelastic media, with Convolution PML absorbing conditions.

Meshing is based for instance upon GmshCubitGiD or a simple internal mesher provided with the package, and the acoustic/(an)elastic/poroelastic solvers are based upon the spectral-element method. The package may also be used to calculate finite-frequency kernels and has full adjoint capabilities. Convolution PML absorbing conditions are used to efficiently absorb the outgoing wave field on the outer edges of the grid.
