Nektar++
========
Nektar++ is an open-source software framework designed to support the
development of high-performance scalable solvers for partial differential
equations (PDEs) using the spectral/hp element method.

This package consists of a set of libraries (the framework) and a number of
pre-written PDE solvers for a selection of application domains.

The software and User Guide is available for download from

User Guide
----------
Detailed information on compiling, installing and using the software is
available in the User Guide. This document is available as a pre-compiled PDF
from the downloads section of the project website.


Tutorials
---------
A number of tutorials are available, designed to walk the user through the
basics of spectral/hp element methods, through the use of individual solvers and
performing specific types of calculations.

The tutorials are available from <http://doc.nektar.info/tutorials/latest>.

Additional software is also required. This can either be installed system-wide
or it can be downloaded and compiled automatically during the build process.

For more detailed information, please see the User Guide.


Compilation
-----------

Installation
------------

The default installation location is in a `dist` subdirectory of the `build`
directory. This can be changed by setting the `CMAKE_INSTALL_PREFIX` option
using `ccmake`. To install the compiled libraries, solvers and header files, on
