A LSD simulation program is a stand-alone program containing the equations of the model, that is, the possibility to compute the value of a set of variables. The program is endowed with a complete set of simple and intuitive graphical interfaces to manage any possible aspect of simulation models.

### Models' Configurations

An LSD model program allows to define, edit, save and load model "configurations". A configuration consists in the lists of the elements in the model, numerical values for their initialization, running options and documentation.

### Running Simulations

LSD model programs allow to run simulations in a variety of different ways, for speed, information-rich, or for debugging.

### Analyse Results

The data from simulations are loaded into a module allowing to inspect the data produced by one or many simulation runs. The module can generate several types of graphs: time series, cross-section, 2D and 3D scatter plots, frequency histograms. The module is particularly efficient in dealing with massive amounts of data. The module produces graphical files and data files for export.
