Bio-CFD has released the first reproducibility index for CFD simulations in biomedical applications. The index classifies CFD simulations according to their reproducibility criteria to allow the scientific community to save time and effort in building verified and validated CFD simulations. The concept is inspired by a recent study conducted on COVID-19 airborne transmission using CFD. The application issues a unique reproducibility index (URI) to eligible simulations free of charge and it is accessible via this link. The simulation registrar (user) simply fills in some information to a Google form which generates a basic/initial index automatically. Then, our team will evaluate the application and issue the final URI within 48 hours.
