Introduction
GB/T 16656 is a national standard for computer interpretable representation and exchange of product data. Its purpose is to provide an independent
It is a neutral mechanism for any specific system to describe product data throughout the product life cycle. The nature of this description makes it suitable not only for neutral texts
software exchange and is suitable as a basis for implementing and sharing product databases and archives.
GB/T 16656 "Industrial automation systems and integrated product data expression and exchange" consists of the following series.
---Parts 1 to 19 describe the method;
---Implementation methods of Part 20 to Part 29;
---Part 30 to Part 39 conformance testing methods and framework;
---Parts 40 to 59 integrate common resources;
---Integrated application resources from Part 100 to Part.199;
---Part.200 to Part 299 Application Agreement;
---Parts 300 to 399 Abstract Test Suite;
---Part 400 to Part 499 application modules;
---Parts 500 to 599 apply interpretation structures;
---Parts 1000 to.1999 application modules.
This document is part of the Integrated Resources series. This document is mainly divided into.
---mesh_topology_schema (mesh topology mode);
---mesh_connectivity_schema(mesh connection mode);
---mesh_function_schema (mesh function mode).
Figure 1 uses the EXPRESS-G language to represent the patterns in this part of the standard and other patterns that define the integration resources of this standard.

Many applications today must process large amounts of data, which is digital in nature; data volumes can be measured in gigabytes, in
In some cases it is even measured in terabytes. Here, typical examples include computational fluid dynamics, dynamic simulation of vehicle behavior, and
Process a variety of experimental data from global weather measurements.
The main concern in processing this type of data is the optimized representation and structure of the data for transmission and storage; as part of this optimization process, the data is dumped
Prefers to be stored in large arrays. Within that large array, any specific data element can be referenced by a simple index within the array.
When data is part of a computer simulation, such data is usually associated with some kind of grid (structured or unstructured) that can be tied to
It is fixed to the vertices or elements of the mesh, and simpler meshes can usually be represented by indexing. In this part, the calculation flow is mainly used
Examples from the field of body dynamics.
This document provides a common, application-independent way of representing indexable data and grids.
