Virtamallinnus

Virtamallinnus, or virtual modeling, is the creation and use of digital representations of real objects, processes, or systems. These models can be simple geometric representations or complex, data-driven simulations that update as new information becomes available. The practice typically combines data from CAD drawings, building information models (BIM), geographic information systems (GIS), sensor networks, and other sources to simulate behavior, performance, and scenarios.

Methods include geometric and parametric modeling, data integration, and numerical simulations such as finite element analysis, computational fluid dynamics, and agent-based or discrete-event simulations. Calibration and validation against empirical data are common, and the most advanced form is a digital twin, which links the virtual model to its physical counterpart through real-time data streams for monitoring, prediction, and control.

Virtamallinnus is applied in engineering, product development, construction, manufacturing, urban planning, energy, transportation, healthcare, and education. It enables virtual prototyping, performance optimization, predictive maintenance, energy analysis, risk assessment, and scenario planning. Potential benefits include faster development cycles, cost savings, reduced risk, and better decision-making; challenges include data interoperability, data quality and governance, privacy and security, model validation, and the need for skilled personnel and computing resources.

Historically, virtamallinnus grew from computer-aided design and simulation, expanding significantly with the rise of IoT, cloud computing, and the broader adoption of digital twin concepts in the 2010s and beyond.
