Build Status

This README file contains brief information. More details are found in the Wiki pages.

The latest revision of the code can be obtained using subversion:

svn co https://github.com/gismo/gismo/trunk gismo

or using git:

git clone git@github.com:gismo/gismo.git

or as a zip file:

Prerequisites

• Operating systems:

  • MS Windows
  • Linux
  • MacOSX

• Configuration: CMake 2.8.8 or newer.

• Compilers tested include recent versions of

  • GNU GCC
  • MS Visual C++
  • Clang
  • Intel C++ compiler
  • Mingw64

• Recommended:

  • Paraview for visualization.

Compilation

The compilation requires configuration using CMake at a new, empty folder (in-source builds are disabled).

• On Linux/MacOSX: A Unix makefile exists in the root source folder. Running "make" creates a sub folder named "build" and executes CMake and compilation inside that folder. Alternatively, choose your own build folder and execute CMake pointing to the sources.

• On MS Windows: Run cmake-gui tool (from an environment that is configured with your compiler) o generate makefiles (or Visual Studio project). Then execute the make tool to launch compilation. Alternatively, use the QtCreator GUI and open the CMakeLists.txt file on the root folder to create a QtCreator project.

After successful compilation a dynamic library is created in ./lib and executable example programs are output at the ./bin subdirectory of the build folder.

Additionally, if Doxygen is available on the system one can execute (eg. on Linux):

make doc

to obtain the Doxygen documentation in HTML format. The main doxygen page is at ./doc/html/index.html.

Configuration Options

The available options are displayed at CMake configuration. Short description and default setting follows:

• CMAKE_BUILD_TYPE Release

  Available values are the standard CMake build configurations: Debug, Release, RelWithDebInfo, MinSizeRel.

• GISMO_COEFF_TYPE double

  The arithmetic type to be used for all computations. Available options include double, long double, float.

• GISMO_EXTRA_DEBUG OFF

  If set to ON additional debugging tools are enabled during compilation. These include checked iterators for GCC and MSVC compilers and call stack back-trace printout when a runtime exception occurs.

• GISMO_BUILD_LIB ON

  If enabled a dynamic library is created using GISMO_COEFF_TYPE arithmetic. A target for a static library named gismo_static is also created but not compiled by default.

• GISMO_BUILD_EXAMPLES ON

  If enabled the programs in the examples folder are compiled, and executables are created in build-folder/bin.

• GISMO_BUILD_UNITTESTS OFF

  If enabled the tests in the unittests folder are compiled, and an executable is created in build-folder/bin.

• GISMO_BUILD_AXL OFF

If enabled the plugin for Axel modeler is compiled (requires Axel).

• GISMO_WITH_PSOLID OFF

  If enabled the extensions using functionalities of Parasolid geometric

kernel are compiled.(requires Parasolid).

• GISMO_WITH_ONURBS OFF

  If enabled the extension for reading and writing of Rhinoceros' 3DM is compiled.

• CMAKE_INSTALL_PREFIX (system dependent)

  The location for installation of the library, e.g. /usr/local on some Linux systems.

Directory structure

The source tree consists of the following sub-folders:

• src

Contains all source files. Code is partitioned into modules. Currently eleven modules are present as sub-folders:

• gsCore
• gsMatrix
• gsNurbs
• gsHSplines
• gsModeling
• gsAssembler
• gsSolver
• gsPde
• gsTensor
• gsIO
• gsUtils

• examples

  Examples of usage, small programs and tutorials.

• unittests Unittests for some parts of the codebase.

• filedata

  Data files in the XML format the G+Smo can read and write.

• extensions

  Optional additional features that can be compiled along G+Smo.

• plugins

• cmake

  Cmake configuration files.

• doc

  Files related to doxygen documentation.
