PyGRT : An Efficient and Integrated C/Python Package for Computing Synthetic Seismograms, Strain, Rotation and Stress Tensor in a Layered Half-Space Model (Dynamic & Static Cases)
-
PyGRT now can compute following properties in both dynamic and static case.
✔️ Displacements and its spatial derivatives
✔️ Strain Tensor
✔️ Rotation Tensor
✔️ Stress Tensor -
At present, PyGRT can run on
✔️ Linux
✔️ MacOS
✔️ Windows -
PyGRT is extremely easy to install by distributing pre-built binary files.
-
PyGRT now supports the model with liquid layers.
-
PyGRT is still evolving, and more features will be released in the future.
-
Surface wave modules will be released soon.
