Introduction

Industrial facilities generate information throughout their entire lifecycle. Engineering teams create drawings, 3D models, equipment specifications and design documents. During operation, sensors and control systems generate another stream of information about temperatures, pressures, flow rates, vibration and equipment condition. A digital twin brings these different information layers together to create a digital representation that can remain connected to the physical asset.

A digital twin is more than a 3D model. A design model can describe geometry, but a useful operational twin can also connect engineering information with asset data, live or historical operating information, analytics and maintenance records. The distinction is important because a plant model does not automatically become a digital twin simply because it is three-dimensional.

At ProSIM, we approach digital twin development from an engineering and simulation perspective. We combine engineering models, asset information, simulation, Industrial IoT, AI/ML and Building Information Modeling where the project requires these capabilities. Our objective is to create a practical digital representation that supports engineering, operations, maintenance and lifecycle decision-making.

What Is a Digital Twin?

A digital twin is a digital representation of a physical asset, system or facility that is connected to information about the real-world object. Depending on the application, this can include geometry, engineering data, sensor information, maintenance history, operating conditions and analytical models.

The level of connection can vary. A simple digital representation may primarily provide structured asset information and visualization. A more advanced twin can receive real-time Industrial IoT data, run simulation or reduced-order models, apply analytics and support predictive maintenance.

This is why digital twin technology should be viewed as an information and engineering architecture rather than a single software feature. The technology becomes valuable when the information is connected in a way that answers real operational or engineering questions.

Digital Twin vs 3D Model

A 3D plant model and a digital twin can share the same geometric foundation, but they serve different purposes. A 3D model is primarily a representation of physical geometry and design information. A digital twin extends that representation by connecting it with information about the physical asset during its lifecycle.

Our 3D plant modelling work can provide an important foundation for a digital twin when the model contains reliable geometry, equipment identification and structured engineering information. The supplied 3D modelling material also emphasizes that a design model should not automatically be called a digital twin because a twin may require operational data and ongoing synchronization with the physical asset.

At ProSIM, we therefore treat the engineering model as one layer of the twin rather than the entire twin. This distinction helps us define the required data, interfaces and analytics before building the solution.

Why Digital Twin Services Matter for Industrial Assets

Industrial organizations need visibility across engineering, operations and maintenance. Information can otherwise become fragmented between CAD systems, plant databases, maintenance systems, documents and operational technology. Digital twin services can help connect these information sources into a more contextual representation of the physical asset.

• Provide a common digital view of equipment and plant information.
• Connect engineering geometry with asset tags and technical information.
• Bring operational data into an engineering context.
• Support condition monitoring and predictive maintenance workflows.
• Enable virtual experimentation and scenario analysis.
• Improve access to information for engineering, maintenance and operations teams.
• Create a structured foundation for future digital engineering initiatives.

The value depends on the quality and relevance of the information connected to the twin. A sophisticated interface cannot compensate for inaccurate asset data, inconsistent identifiers or missing engineering information.

How a Digital Twin Works

A typical digital twin architecture can be understood as several connected layers. The first layer is the physical asset. The second is the digital representation, which may include 3D geometry and engineering information. The third consists of data connections, such as sensors, Industrial IoT systems, enterprise databases and maintenance records. Analytical models then use these inputs to generate insights.

The exact architecture varies by application. Some twins may focus on visualization and asset information, while others may include simulation, AI/ML, reduced-order models and real-time monitoring. The architecture should therefore be defined around the business and engineering questions the organization needs to answer.

Engineering Model as the Foundation

A reliable digital twin needs a reliable representation of the asset. For industrial facilities, this may begin with 3D plant modelling, equipment data, piping information, structural information, instrumentation and other engineering documentation.

Our plant modelling experience supports this foundation by organizing geometry and engineering information into a coordinated digital representation. A well-structured model can provide the spatial context needed to understand where equipment is located, how systems connect and which components are associated with particular engineering information.

For existing facilities, as-built information is especially important. Drawings may differ from the current physical arrangement, so surveys, scans, photographs and field verification can be used to establish a more accurate digital representation. This can improve the reliability of the model used as part of a digital twin.

Asset Data Integration

Geometry alone does not provide enough information for many operational use cases. Equipment tags, component types, specifications, design conditions, maintenance records and operational data can provide the context needed to understand what a particular object represents and how it behaves.

Digital twin services can therefore include data integration between engineering systems and operational information sources. Consistent identifiers are important because the same asset may appear in multiple systems under different names or structures.

At ProSIM, we focus on connecting the engineering representation with structured asset information so that the digital environment can support more than visualization. The goal is to create a usable information layer around the physical asset.

Industrial Digital Twin

An industrial digital twin applies the digital twin concept to industrial equipment, facilities and processes. Applications can range from individual machines to complete plants. The scope depends on the operational question and the level of information available.

An industrial digital twin can combine 3D geometry, engineering data, operational measurements, maintenance information and analytical models. For a process facility, the twin may provide a spatial view of equipment and piping while also displaying selected operating parameters.

For rotating equipment or other critical machinery, the focus may be on condition monitoring, predictive analytics and remaining useful life. The same digital twin technology can therefore support different workflows depending on the asset and its operational priorities.

Digital Twin Software

Digital twin software is the technical layer used to store, visualize, connect, analyze or manage the information associated with a twin. The software environment can include 3D visualization, databases, IoT connectivity, analytics, simulation engines and interfaces to enterprise systems.

There is no single digital twin software architecture that fits every industrial application. The required components depend on the asset, data sources, existing IT and OT systems, cybersecurity requirements, engineering applications and intended use cases.

At ProSIM, we focus on the engineering problem first and then consider the software and integration requirements. This helps avoid selecting a technology stack before the organization has defined what the twin actually needs to accomplish.

Digital Twin Platform

A digital twin platform can provide the environment in which asset information, 3D models, operational data and analytical services are brought together. Depending on the project, the platform may support visualization, data integration, analytics, simulation and user access.

The platform should make information understandable to the people who use it. Engineers may need detailed technical information, maintenance teams may need equipment condition and service history, while management may need high-level performance indicators.

A useful digital twin platform therefore needs a clear information structure and appropriate user access rather than simply presenting a visually impressive 3D environment.

Digital Twin Technology and Real-Time Data

Digital twin technology becomes particularly powerful when the digital representation is connected to data from the physical asset. Industrial IoT systems can collect sequential measurements from sensors distributed across equipment or facilities. These data streams can then be connected to the relevant digital objects.

At ProSIM, our digital twin capability includes Industrial IoT integration and the analysis of sequential sensor data. This creates a pathway from physical equipment to digital representation and then to analytics.

Real-time data can support monitoring, but the value of real-time connectivity depends on the engineering question. Not every parameter needs to be updated continuously. The data architecture should prioritize information that can influence maintenance, performance, safety or operational decisions.

Reduced-Order Models for Real-Time Simulation

Detailed CFD and FEA models can provide high-fidelity engineering information, but their computational requirements can make continuous real-time use impractical for some applications. A reduced-order model can provide a faster approximation of selected system behaviour when developed appropriately.

At ProSIM, we develop reduced-order models to support real-time simulation. These models can be designed to run quickly enough for applications where immediate virtual experimentation or rapid decision-making is required. The supplied ProSIM material describes reduced-order modelling as a way to convert dense physics calculations into fast-running numerical frameworks and deploy them on edge hardware or in the cloud.

This creates an important connection between simulation and digital twin technology: detailed engineering simulation can inform a faster operational model, which can then be used alongside live data.

AI/ML and Digital Twin Analytics

A digital twin can use artificial intelligence and machine learning to identify patterns in operational data. AI/ML models can support anomaly detection, predictive maintenance and remaining useful life estimation when sufficient quality data and appropriate modelling methods are available.

At ProSIM, we use AI/ML with Industrial IoT data to help transform operational measurements into actionable insights. We can calibrate analytical approaches to the equipment and application rather than treating the same model as universally applicable.

AI should complement engineering knowledge rather than operate independently of it. Physical constraints and engineering relationships can help ensure that data-driven predictions remain meaningful for the equipment being studied.

Hybrid Digital Twin: Physics-Based and Data-Driven Models

A hybrid digital twin combines physics-based models with data-driven methods. Physics-based models describe how a system should behave according to engineering principles, while data-driven models can capture patterns associated with actual operating behaviour and equipment condition.

At ProSIM, we use hybrid modelling to combine physical principles such as fluid dynamics, structural mechanics and thermodynamics with AI and machine learning insights. This approach can help connect engineering theory with real-world operating data.

The benefit of a hybrid approach depends on the quality of both sides. A physical model needs suitable assumptions and inputs, while a data-driven model needs representative and reliable data. The combination should be designed around the engineering objective.

Predictive Maintenance with Digital Twin Services

Predictive maintenance is one of the major operational applications of digital twin services. Instead of relying only on fixed maintenance intervals or responding after a failure, organizations can use equipment data and analytical models to identify early indications of degradation.

A digital twin can provide the context needed to interpret those signals. Sensor data can be associated with the relevant equipment, engineering limits and historical behaviour. AI/ML models can then support anomaly detection or remaining useful life estimation.

At ProSIM, our digital twin approach includes predictive AI/ML and remaining useful life calculations. We use the digital environment to connect asset information, sensor data and engineering models so that maintenance insights can be interpreted in context.

Digital Twin for Asset Performance and Optimization

Monitoring is only one part of a digital twin. When simulation and analytics are connected to the twin, the environment can also support performance optimization and virtual experimentation.

For example, an engineer may want to evaluate how an operating parameter affects system performance before making a change in the physical plant. A suitable reduced-order or physics-based model can provide a virtual environment for such a study.

The ProSIM digital twin material describes closed-loop optimization in which analytical frameworks can help identify improved operating parameters. In practice, the degree of automation and connection to control systems should be determined by the application’s technical, safety and governance requirements.

BIM Integration with Digital Twins

Building Information Modeling provides a structured approach to creating and managing information associated with built assets. BIM and digital twin workflows can complement each other when engineering geometry and structured information are connected to operational systems.

Our digital twin material includes BIM integration and as-built digital threads, where structural and engineering BIM information can be connected to virtual representations and maintenance records.

BIM engineering information can therefore provide part of the information foundation for a digital twin, particularly when asset identifiers, geometry and metadata are consistently structured.

As-Built Digital Twin Development

For an existing facility, the digital twin should reflect the physical asset rather than an outdated design intent. As-built digital twin development can begin with drawings, surveys, laser scans, photographs, equipment records and field verification.

At ProSIM, we can connect as-built engineering information with a digital representation of the facility. This is especially useful for brownfield projects, where modifications and maintenance activities depend on accurate knowledge of existing conditions.

The digital representation can then become a foundation for connecting asset information, operational data and future engineering changes.

Digital Twin for Engineering and Maintenance Collaboration

Engineering and maintenance teams often work with different information sources. Engineers may use drawings, 3D models and specifications, while maintenance teams rely on work orders, inspection records and equipment history.

A digital twin can provide a common contextual layer between these groups.

A maintenance engineer can locate an asset within a 3D environment and access associated information. An engineering team can use the same asset identity to connect design information with operational history. This shared context can reduce the effort required to find and interpret information.

At ProSIM, we aim to create this connection between engineering information and operational use cases so that the digital twin remains useful across the asset lifecycle.

Enterprise Digital Twin

An enterprise digital twin extends the concept beyond an individual asset or isolated engineering application. It can provide a shared information environment across multiple facilities, asset classes, departments and business processes.

An enterprise digital twin may connect engineering, maintenance, operations and management information through common asset identities and data structures. The architecture needs to be scalable, but scalability should not come at the expense of data quality or usability.

The first step is often to establish a well-defined pilot around a meaningful asset or process and then expand the architecture as the organization develops confidence in the information model and use cases.

Digital Twin Consulting

Digital twin consulting can help organizations define what should be included in a twin, how data should be structured and which use cases should be developed first. Consulting can cover technology selection, architecture, engineering-data requirements, integration, simulation and lifecycle applications.

At ProSIM, our digital twin consulting approach starts with the engineering and operational problem. We examine the available models, asset data, sensor information and existing systems before defining the required architecture.

This approach helps distinguish between a digital twin that is technically possible and one that is practically useful for the organization.

6. Validate and Govern

Check data quality, model behaviour, synchronization, user access and engineering assumptions. Establish ownership and update procedures.

7. Scale the Twin

Once the initial workflow is proven, expand to additional assets, systems or facilities where the same information architecture can provide value.

Common Digital Twin Challenges

• Treating a 3D model as a complete digital twin without connecting operational information.
• Building the technology before defining the engineering or operational use case.
• Inconsistent asset tags and identifiers across engineering and operational systems.
• Poor-quality or incomplete as-built information.
• Connecting large volumes of data without defining which information is actually useful.
• Using AI/ML without sufficient or representative historical data.
• Expecting high-fidelity CFD or FEA models to operate continuously without considering computational cost.
• Failing to define responsibility for maintaining the digital representation as the physical asset changes.

At ProSIM, we address these challenges by starting with the engineering workflow and the intended use case. The digital representation, data integration and analytics are then developed around that requirement.

How to Choose a Digital Twin Partner

When selecting a digital twin company or engineering partner, organizations should look beyond visualization capability. The partner should understand engineering data, asset information, simulation, integration and the operational context in which the twin will be used.

• Engineering and industrial-domain knowledge.
• Experience with 3D plant models and as-built information.
• Understanding of asset-data structures and information integration.
• Capability in simulation, reduced-order modelling and analytics where required.
• Experience with Industrial IoT and AI/ML integration.
• Ability to work with existing engineering and enterprise systems.
• Clear approach to validation, governance, revision and lifecycle updates.

At ProSIM, we combine engineering simulation and digital engineering knowledge with digital twin development. We use this combination to keep the digital twin connected to the engineering reality of the asset.
