According to the pypi site(http://pypi.python.org/pypi/escript/):

   escript is a python based environment for implementing
mathematical models in particular those based on coupled, non-linear,
time-dependent partial differential equation. Parallelization with
both OpenMP and MPI is supported.

 The 3.0 user's guide describes it as:

 It consists of four major components

   * esys.escript core library
  * finite element solver esys.finley (which uses fast
vendor-supplied solvers or our paso linear solver library)
  * the meshing interface esys.pycad
  * a model library.

 There is a Finite Element code implemented with escript called Finley.
 There looks to be support for gmsh (mesher) and output visualization
using matplotlib (matlab-like plotter) and VTK (visualization
toolkit).
