Safe Public Environment

Water droplets are one of the primary transmission vectors of the SARS-CoV-2 coronavirus that leads to COVID-19. Increasingly, scientific communities claim that the virus can spread through airborne particles. While coughing or sneezing projects large numbers of respiratory droplets, talking and breathing also releases them. These droplets are potentially transported through the air, carried by the surrounding airflow, and can be inhaled by others. They can also deposit on surfaces that other people touch, leading to further infection. Furthermore, individuals can be contagious for several days before symptoms manifest, and people with mild or asymptomatic cases may not realize they are infected at all.

In those conditions

• Hospitals have to ensure that vulnerable patients and staff are not put at risk.
• Universities, administrative buildings and office spaces have to re-open safely.
• Cultural and touristic venues, undergoing a critical economic slump, now have to take into account this new risk to welcome back the public (concert and exhibition halls, museums, hotels, shopping malls, indoor stadiums, etc.).
• The transportation sector is also going through an economic slowdown—restarting the economy will require ramping up domestic and international transport infrastructure (air & train), while securing the confidence of the passengers.

 

Safe Public Environment solution, powered by the 3DEXPERIENCE platform, provides simulation capabilities that enable the analysis of contamination risks and a science-based support to design palliative measures.

Safe Public Environment leverages cloud computing to enable fast simulation of complex environments without the need for on-site hardware, minimizing the disruption of working from home and permitting rapid scale-up for new ideas. The Dassault Systèmes 3DEXPERIENCE platform allows users to collaborate without being physically present and to quickly assemble design data into simulation-ready projects. Images and video renderings are key to explaining propagation to the public and reassuring customers, passengers, staff and investors.

 

• Quick 3D Virtual Twin modeling of existing or future facilities.
• Intelligible information visualization and understanding of turbulent airflow schemes,  article motion and tracking, as well as surface deposition in complex environments within the virtual twin of the facility.
• Quick identification, evaluation and validation of mitigation actions.
• Simulation of multiple scenarios to evaluate the impact of each mitigation action and decision.
• Education and customer reassurance.
• Clear, easy-to-understand images or video renderings to support communication to authorities and the public.
