4 Information requirements

This clause specifies the information requirements for the mesh function application module.

The information requirements are specified as a set of units of functionality, application elements, and application assertions. These assertions pertain to individual application entities and to relationships between application entities. The information requirements are defined using the terminology of the subject area of this application module.

1. - A graphical representation of the information requirements is given in annex C.
2. - The mapping specification is specified in 5.1 which shows how the information requirements are met using the integrated resources of this International Standard. The use of the integrated resources introduces additional requirements which are common to application modules and application protocols.

4.1 Units of functionality

This subclause specifies the units of functionality (UoF) for the mesh function application module as well as any support elements needed for the module definition. This part of ISO 10303 specifies the following units of functionality:

• Mesh_function

This part of ISO 10303 uses the following units of functionality:

• Maths_function;
• Mesh;
• Tabular_function.

The units of functionality and a description of the functions that each UoF supports are given below.

4.1.1 Mesh_function

The Mesh_function UoF defines a mesh function and references the mesh that is used and the control values. The Mesh_function UoF also defined the 'basis' for each cell, i.e. the method of interpolation or extrapolation from the control values.

The following application objects are used by the Mesh_function UoF:

• Mesh_function;
• Mesh_function_basis.

4.1.2 Maths_function

This UoF is defined in the Maths_function module. The following application entities from this UoF are referenced in the Mesh function module:

• Maths_function.

4.1.3 Mesh

This UoF is defined in the Mesh module. The following application entities from this UoF are referenced in the Mesh function module:

• Mesh.

4.1.4 Tabular_function

This UoF is defined in the Tabular_function module. The following application entities from this UoF are referenced in the Mesh function module:

• Table.

4.2 Required AM ARMs

EXPRESS specification:

*)
USE FROM Maths_function_arm -- Maths_function
  (Maths_function);
USE FROM Mesh_arm -- Mesh
  (Mesh);
USE FROM Tabular_function_arm -- Tabular_function
  (Table);

4.3 ARM type definitions

• none.

4.4 ARM entity definitions

• Mesh_function
• Mesh_function_basis

4.5 ARM rule definitions

• none.

4.6 ARM function definitions

• none.
