Datasets

To run a simulation, it is necessary to provide a simulation model and input timeseries (see modules chapter for which timeseries are needed). A simulation model can be constructed via API (see example), or via built-in loaders.

LTMV10 loader

In order to integrate with older systems, Trident supports loading the simulation model and timeseries from a LTMv10 dataset. Here we provide an overview of the subset of files Trident makes use of, and that needs to be provided in order for the different modules to function properly.

The files can be made manually by a user (or their internal system), by a ltm application or by LTM api.

PRISAVSNITT.DATA
