Spatial Models and Masks in Indoor Anaysis for the Spread of COVID-19

The ability to model and visualize the spread of particles can help when identifying solutions for buildings, like maximum occupancy or sufficient ventilation. Face masks have been shown to slow or stop the spread of airborne COVID-19 droplets and aerosols. We introduce a Cell-DEVS model for rapidly prototyping viral particle spread and the effect of various face masks. We also build scenarios for the model to examine the effectiveness of all types of masks and respirators recommended by the World Health Organization on the spread of viral particles in an indoor environment.
