Escript is a programming tool for implementing mathematical models in Python using the finite element method (FEM). Because users do not access the data structures it is very easy to use and scripts can run on desktop computers as well as highly parallel supercomputer without changes. Application areas for escript include earth mantle convection, geophysical inversion, earthquakes, porous media flow, reactive transport, plate subduction, erosion, and tsunamis.

Scripts can be executed in parallel (on varying numbers of threads or nodes) without any special modifications.

Escript now includes the esys.downunder module for 3D inversion of geophysical data sets. The current version supports gravity, magnetic and joint inversion.

This package contains the commands and libraries for Python3 with both OpenMP threading and MPI multiprocess support.
