A Physical_space_topology is a Classification that specifies the dimensionality, the continuity, and the sub-divisions of a Physical_space.
EXAMPLE - An edge (with topological dimension of 1) is a Topological_object.
The relationship between:
- the Product_feature_space that is the set of cross sections along beam XB_123; and
- the Topological_object that is an edge,
that indicates the set of cross sections is an edge, is a Physical_space_topology.
EXAMPLE - A face (with topological dimension of 2) is a Topological_object. A division of a face into the triangles and quadrilaterals of mesh FB_027 is a Topological_object.
The relationship between:
- the Product_feature_space that is the set of normal fibres over shell PLT_24, and
- the Topological_object that is mesh FB_027,
that indicates the set of fibres has the sub-divisions of the mesh, is a Physical_space_topology.
