The term "digital representation" in virtual models refers to the creation of a digital twin or simulation that mimics the physical counterpart of an object, process, or system. This representation involves the use of 3D modeling and data integration to create a virtual version that can be analyzed, tested, or modified without impacting the actual system. Digital representations enable better visualization, improved decision-making, and enhanced collaboration among stakeholders by allowing them to view and interact with models in a virtual environment before physical implementation.
