Simulations Make Classes Safe in the Pandemic

More than 19 million students, who could not go to school since March 2020 due to the COVID-18 epidemic, made their way back to their classrooms for face-to-face education after a long break with the reopening of schools. But emerging new variants are causing disease rates to rise again worldwide during this period. While students try to continue their education as normal by avoiding the risk of contamination, ensuring the safety of them and school personnel has once again become one of the top priorities in Turkey.

Seeking to contribute to the safe return of students and staff to schools, Dassault Systèmes leverages simulation solutions long used to optimize industrial design, revealing how they can create healthier and safer classrooms with the insights they provide in terms of regulation, design, and precautions.

Understanding the physics of airflow and the directions in which potentially morbid airborne droplets will travel can help determine what can be done to mitigate their effects. Powered by the 3DEXPERIENCE platform, Dassault Systèmes' SIMULIA apps can play a role in improving student safety during the pandemic, using highly accurate Computational Fluid Dynamics (CFD) simulation. To show what the application can do in this direction, Dassault Systèmes used SIMULIA to reveal the invisible risks and viable solutions in a classroom.

The simulations revealed that wearing a mask reduces the spread of droplets from one pupil to another. However, the same simulations also showed that in poorly ventilated classrooms, small droplets can remain suspended in the air and then be deposited on furniture or students. To demonstrate how the risk of airborne virus transmission can be further reduced, Dassault Systèmes simulated a classroom with an infected student and determined which classroom layout minimizes the risk of infection among students, with different ventilation, seating arrangements, and airflow paths.

Using CFD simulation and cutting-edge engineering methods, Dassault Systèmes has demonstrated how a previously unassessed, irregular seating plan can yield more effective results. Although there is no solution to 19 percent prevent a person from catching COVID-100, the results showed that simulations allow engineers to design a safe environment as much as possible by evaluating a space in the most accurate way.

In addition to making classrooms safer, Dassault Systèmes' SIMULIA applications and other services are also used to help everyone from civil engineers to facilities managers re-evaluate the public and workplace spaces. Thus, simulation applications enable safer environments to be created in hospitals, airports, factories, offices and living spaces during the pandemic period.
