Definition

For a <Finite Element Mesh> instance F with a <Mesh Face Table> component M, the following conditions shall hold.

1. Each <Vertex> component of F shall appear exactly once as a component of F.

2. No two <Vertex> components of F shall occupy the same position in space.

3. If F has a <Property Table> component P such that P's <Classification Data> classifies it as an ECC_MESH_NODE_PROPERTY_SET, P shall be the only <Property Table> component of F that is so classified, and shall have the structure specified in the definition of the <Finite Element Mesh> class for a <Property Table> of its classification.

4. If F has a <Property Table> component P such that P's <Classification Data> classifies it as an ECC_MESH_FACE_PROPERTY_SET, P shall be the only <Property Table> component of F that is so classified, and shall have the structure specified in the definition of the <Finite Element Mesh> class for a <Property Table> of its classification.

5. If F has a <Property Table> component P such that P's <Classification Data> classifies it as an ECC_MESH_SOLID_SET, P shall be the only <Property Table> component of F that is so classified, and shall have the structure specified in the definition of the <Finite Element Mesh> class for a <Property Table> of its classification.

6. If F has a <Property Table> component P1 such that P1's <Classification Data> classifies it as an ECC_MESH_SOLID_PROPERTY_SET, P1 shall be the only <Property Table> component of F that is so classified, and shall have the structure specified in the definition of the <Finite Element Mesh> class for a <Property Table> of its classification.

Rationale

1. All the <Vertex> components of a <Finite Element Mesh> are required to be distinct in order to form a geometrically valid mesh.

2. The components of a <Finite Element Mesh> are required to comply with the conditions specified in the definition of the <Finite Element Mesh> and <Mesh Face Table> classes.
