Database&Technology--SimuGENS INFECTION

 

In 2014 D&T/SHRAIL developed SIMUGENS, a software for crowd simulation, able to reproduce the behavior of large number of individuals in various situations, successfully used for small and mid scale crowd dynamics analyses.

 

In 2020, following the outbreak of the COVID-19 virus, SIMUGENS has been expanded with a set of functionalities focused on the dynamics of the infections in large crowds and on the evaluation of possible mitigation solutions.

 

SIMUGENS INFECTION can simulate individual infections based on people distance and exposure time as well as infective objects or surfaces, calculating infection rates over time.The SIMUGENS functions for infection simulation include:

• immune and infected people 
• infection%
• exposure time and distance 
• infected objects and areas.

 

Agent-based, continuous-space crowd simulator.Graphical user interface, supporting interactive visual editing.Advanced output, updated in real time, based on 2D layout visualization, data tables, interactive charts.

 

Real-time OpenGL 3D visualization, with color-code results or human-looking crowd representation.

 

Supported file formats

CSV (table data input) DXF

layout import

CSV (table data output)

AVI (2D/3D movie output)

 

System Requirements

Windows XP to 10

2GB RAM 

40 Mb disk space

 

Airflow integration

In order to better represent the possible infection mechanism, SIMUGENS INFECTIONS has been provided with the possibility to import and use airflow data produced by CFD simulations.

 

The airflow information is used to calculate the propagation of droplets produced by infected individuals inside the simulated crowd, allowing a better evaluation of the infection between individuals.

 

The combination of airflow and crowd simulations is a unique possibility to represent together the two complex and non-linear aspects of the infection.
