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).
As far as I understand, xsum_preconditioned_kernels uses the Hessian estimation to calculate the preconditioned kernels. Therefore, I'd expect the preconditioning result's size to be "natural", e.g. 30 m/s for the beta kernel. However, I get kernels whose maximum value is around 10^(-5); could you explain it?
