[CIG-SEISMO] Time series as input

[Stephen Crane]

Hi All,



I am using SPECFEM3D/SPECFEM2D for modelling earthquake ground motions far from the source. As access to larger computing resources is limited for myself I was hoping to reduce the model size. In order to make the model sufficiently small, the source would be outside the model area. Is it possible to use a recorded acceleration time series as an input motion at the edge/corner of the model? Has anyone attempted this or can anyone tell me if this is even a good idea?



I would be gracious for any insight on this.



Regards,
