GLEaMviz Simulator Features

Compartmental Model Builder

The model builder provides a visual modeling tool for designing arbitrary compartmental models, ranging from simple SIR models to complex compartmentalizations.

Design models as flow diagrams, with stylized box shapes that represent the compartments, and links that represent transitions.
Create any structure through click and drag operations.
Specify mobility constraints and whether the compartment refers to clinical cases.
Annotate spontaneous transitions with their rates.
Define infection transitions sources right in the model builder interface.
Specify rates in terms of variables.
Open and save the models, and export them as a PDF or SVG files.

Simulation Wizard

The simulation wizard provides a sequence of panels that lead the user through the configuration of a simulation.

Select or create the compartmental model to use.
Specify the duration of the simulation, the number of runs to perform, seasonality parameters, airplane occupancy rate, and other settings.
Define time-dependent overrides of the variables in the compartmental model.
Specify the initial distribution of the population in the compartments.
Define the initial geographic location of the seed of the epidemic and the date of the start of the outbreak.
Select the compartments to be visualized.

Simulations Manager

The simulations manager provides an overview of the simulations that the user has designed and submitted.

Retrieve the simulations results from the server.
Visualize the retrieved results.
Export the simulation data for analysis in other tools.
Save complete simulation configurations for later use.

Visualizations

The visualization environment combines a multi-scale map and a set of incidence curves.

Display infected census areas colored according to the size of the infection.
Animate the evolution of the epidemic.
Control the focus and level of detail of the visualization.
Get details on census areas.
Show long-range mobility links used by infected people.
Compare plots of the instantaneous and cumulative number of new individual entering the selected compartments.
Select the geographic scale of the plots for which these curves are shown, ranging from global, to specific continents, regions, countries, down to specific census areas.
