Case Study: Saint-Louis Hospital improves dialysis unit infection safety with Dassault Systèmes airflow simulations

Saint-Louis Hospital airflow simulations | Customer Story

Saint-Louis Hospital, a major public hospital in Paris, was challenged by the airborne transmission of viruses among immunocompromised patients in its open-plan dialysis unit. To understand the spread of pathogens, the hospital partnered with Dassault Systèmes to create a virtual twin of the department and perform airflow simulations using the SIMULIA Fluids application on the 3DEXPERIENCE platform.

Dassault Systèmes implemented a Virtual Twin as a Service (VTaaS) solution, building a full-scale digital model of the room to simulate particle contamination under various scenarios. The simulations identified insufficient airflow and specific zones where virus particles clustered. This led to proactive measures, including improved ventilation and new policies, which successfully normalized the air and eliminated the hyper-concentration of viruses. The project also used an innovative augmented reality tool to visually demonstrate the risks to staff, significantly raising awareness.
