[CIG-SEISMO] simulation of seismic wave propagation excited by a force

[Yingzi Ying]

Hi all,

I am trying to use specfem3d to simulate waves excited by a vertical 
force with user-defined source forms such as ricker wavelet.

I tried to do it through adjoint simulation by setting 'SIMULATION_TYPE 
= 2' and put source position at STATIONS_ADJOINT and receivers at 
CMTSOLUTION. But I failed.

Does anyone have an idea or suggestion how to do active simulations with 
specfem3d?

Thanks in advance.

Best regards,
Yingzi
