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 http://www.nektar.info/.
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.
Pre-requisites
Nektar++ requires the following software to be installed on the users system:
- CMake
- BLAS/LAPACK
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
On most UNIX-based systems a default compilation can be performed using the following commands from the top-level of the source tree:
mkdir build
cd build
cmake ..
make
To alter the build configuration (for example, to enable parallel execution
support) we recommend using the ccmake
command instead of cmake
.
For more detailed operating-system specific instructions, please see the User Guide.
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
UNIX-based systems run:
make install
