Welcome to the DSM world.

This is a software for computing synthetic seismograms in a spherically symmetric, transversely isotropic (TI) model using the Direct Solution Method (DSM).

This package is a bundle of 3 separate programs: tish, tipsv, and spcsac. You must build each program separately.

% cd tish-mpi
% make
% cd ../tipsv-mpi
% make
% cd ../spcsac
% make

Important note

If you compute only the toroidal contribution to the transverse component and the spheroidal contribution to the radial component, this will lead to errors on the order of 1% or more. Therefore you must include the toroidal contribution to the radial displacement and the spheroidal contribution to the transverse component.
