Software structure

Required characteristicsq• Possibility of replacing a method by another• Easy integration of new functionalities• Independence of the different physical models• Independence of the different physical models

Corresponding organization : a modular structure• Different functionalities are separatedDifferent functionalities are separated• No dependencies between the different physical models• Dependencies between modules are simple and well-identified• This modularity is regularly checked

Project management

Documentation• User guides

– How to use the platform (installation, execution, exploitation of results))

– Scientific foundations of the implemented methods• Technical documentation for developers

D i ti f th i d l– Description of the main common modules– Details of the specific implementations– Description of procedures (version control, testing)

• Standard tools– UML modeling– Automatic documentation extraction– Automatic documentation extraction

Project management

Internal communication• GForge

– Tasks managerB t k– Bugs tracker

• Diffusion lists• Frequent meetings

Using the platform

A convenient interface for input parametersp p• XML format• Friendly user interface

10

Using the platform

Efficient tools for parametric studiesp• Automatic generation of parametric studies

– Parameters filesR i b t h– Running batch

• Results exploitation : automatic crossing of results from several executions
