SPECFEM3D_Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, poroelastic or seismic wave propagation in any type of conforming mesh of hexahedra (structured or not).
I wanted to know what are the units of the isotropic sensitivity kernels (alpha, beta, rho) calculated by SPECFEM. In the manual, the units of the anisotropic kernels are noted, but not the isotropic ones. Are they s/km^3 as in Tromp et al. 2008?
