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 . 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
