Welcome to SimPhoNy’s documentation!


The native implementation of the SimPhoNy cuds objects and io code (http://www.simphony-project.eu/).

Build status Test coverage Documentation Status


Simphony-common is hosted on github: https://github.com/simphony/simphony-common


  • enum34 >= 1.0.4
  • stevedore >= 1.2.0
  • numpy >= 1.4.1

Optional requirements

To support the cuba-generate script the following packages need to be installed prior to installing Simphony:

  • click >= 3.3
  • pyyaml >= 3.11
  • tabulate >= 0.7.4

To support the HDF5 based native IO:

  • PyTables >= 3.1.1

To support the documentation built you need the following packages:

  • sphinx >= 1.2.3
  • sphinxcontrib-napoleon >= 0.2.10
  • mock


Packages that depend on the optional features and use setuptools should append the H5IO and/or CUBAGen identifier next to simphony in their setup_requires configuration option. For example:

install_requires = ["simphony[H5IO, CUBAGen]"]

Will make sure that the requirements of H5IO and CUBAGen support are installed. (see setuptools extras for more information)


The package requires python 2.7.x, installation is based on setuptools:

# build and install
python setup.py install


# build for in-place development
python setup.py develop


To run the full test-suite run:

python -m unittest discover


To build the documentation in the doc/build directory run:

python setup.py build_sphinx

If you recreate the uml diagrams you need to have java and xdot installed:

sudo apt-get install defautl-jre xdot

A copy of the plantuml.jar needs also to be available in the doc/ folder. Running make uml inside the doc/ directory will recreate all the UML diagrams.


  • One can use the –help option with a setup.py command to see all available options.
  • The documentation will be saved in the ./build directory.
  • Not all the png files of the UML diagrams are used.

Directory structure

There are four subpackages:

  • core – used for common low level classes and utility code
  • cuds – to hold all the native cuds implementations
  • io – to hold the io specific code
  • bench – holds basic benchmarking code
  • examples – holds SimPhoNy example code
  • doc – Documentation related files
    • source – Sphinx rst source files
    • build – Documentation build directory, if documentation has been generated using the make script in the doc directory.

SimPhoNy Framework

The simphony library is the core component of the SimPhoNy Framework, infromation on setting up the framework are provided on a separate repository https://github.com/simphony/simphony-framework.
