"Molecular for Blender 3.0+" is an add-on developed by Jacques Lucke and Adrian Felinto, allowing Blender users to simulate molecular dynamics directly within the software. It's a powerful tool for creating realistic animations of particle systems, molecular structures, and more. This add-on seems to be an evolution or continuation of the "Molecular Script" or "Molecular Addon" I mentioned earlier, but with updates and improvements specifically for Blender 3.0 and beyond. It's great to see developers continuously improving and expanding the capabilities of Blender through such add-ons!
