General Information
Overview - ISO/TS 15926-3:2009 (geometry and topology)
ISO/TS 15926-3:2009 is part of the ISO 15926 family for life‑cycle data integration in process plants (including oil and gas). This technical specification defines reference concepts for geometric and topological data, enabling the consistent recording and exchange of geometry, topology and mesh-related information using ISO 15926 data structures. The document ensures representations are compatible with ISO 15926-2 and with first‑order logic, supporting rigorous semantic interoperability.
Key topics and technical requirements
- Geometric and topological concepts: formal definitions needed to represent shapes, connectivity and spatial relationships for plant components.
- Compatibility with ISO 15926-2: concepts are specified so geometric/topological data can be encoded using the ISO 15926-2 data model.
- First‑order logic consistency: modeling rules ensure representations are logically consistent and suitable for semantic reasoning.
- Mesh topology and mesh functions: definitions for mesh elements (nodes, edges, faces), mesh connectivity and functions (fields) defined over meshes.
- Property distribution representation: methods to record how scalar/vector properties (e.g., temperature, stress, material properties) are distributed across mesh elements.
- Recording of mesh topology data: guidelines to capture mesh structure for downstream use in simulation, analysis and visualization.
Note: ISO/TS 15926-3:2009 provides conceptual reference data; it does not prescribe particular file formats or vendor‑specific implementations.
Practical applications
- Integrating CAD, CAE and asset information across the plant life cycle for engineering, procurement, construction and operation.
- Exchanging mesh and simulation result metadata (mesh topology and property distributions) between design, analysis and operations systems.
- Enabling digital twin and simulation workflows that require consistent semantic definitions of geometry and mesh‑based properties.
- Supporting interoperability between engineering software vendors, data repositories and enterprise asset management systems.
Who uses ISO/TS 15926-3:2009
- Plant and process engineers who manage life‑cycle asset data.
- CAD/CAE and digital‑twin software developers and integrators.
- Data architects, semantic modelers and system integrators working on plant information systems.
- Asset owners/operators in oil & gas and process industries seeking standardized geometric and mesh metadata exchange.
