During my stay at the Department of Rock Mechanics at the TU Bergakademie Freiberg I
developed a Gocad-plugin for calculating the change in amplitude of seismic waves during traversal
of an SGrid.
Due to attenuation of rocks, the wave amplitude decreases farther away from the source position.
If the attenuation factor is know, the change in amplitude can be calculated.
The plugin was developed in C++ using Visual Studio 2010. The download link for the
plugin can be found below, this version is for Gocad 2011.3 64-bit. For other version, feel free to
contact me.
