Up to version 0.17, the results of a simulation were saved in a dedicated file from which the various shapefiles associated with each variable were configured. The rows of the attribute table represented the network elements, and the columns represented the different simulation time steps. This structure ultimately proved too rigid for the development of new tools for analysing the results..
Consequently, a radical change has been introduced in version 0.18. The various results requested by each analysis tool are now extracted directly from the .out binary output file created by the latest version of Toolkit 2.3.4. The response is now much faster and the flexibility for any type of query is significantly greater.
In the new results structure, the elements still occupy the rows of the attribute table in the shapefiles, but the columns are now the different quantities associated either with the nodes or with the lines. As time progresses, this table is updated for each time step.
The new structure has made it possible to generate various statistics for each element of the network, taking into account all their time-dependent values throughout the simulation for the selected event. This is done by directly querying the binary results file, without the need to resimulate the scenario.
If at any point the user wishes to access all results, for all elements, magnitudes and time instants, the option to export them all to a CSV file has been added to the Calculate menu.
This new method of storing and displaying results presents a wide range of scenarios, all of which have been successfully resolved. A specific tutorial detailing all the features of the new on-map results analysis tool will be produced shortly.
