ParaGeo has a plug-in functionality which allows user interaction with the data (e.g. variable values, models) during an analysis. The main related data structure is User_import_export_control which is used to define control data relative to the import and export of data during an analysis. Such data may comprise:
•Whether import data, export data or both is performed during the analysis
•The frequency for import/export operations
•The coupling process between the external data and ParaGeo
The User_prompt data structure can be used to change control data; e.g. output of data, termination, time, etc while the analysis is proceeding. The User_prompt data structure is defined in a file "user_prompt.dat" in the same directory as the project file. If the user_prompt.dat file is detected it is read and the control data for the simulation is modified by the user specified data. Once the user_prompt.dat file has been processed it is deleted by the simulation to prevent further processing of this data.
