To understand the different properties used in CAD volume modellers and CAE modellers, the notions of manifold solid and non-manifold objects have to be explained. Mainstream CAD packages (CATIA, NX, Solidworks) use a manifold modelling environment where a set of faces bounding a solid are defined to enclose a bounded partition of the 3D space that represents the physical object. Two adjacent solids have completely independent topological structures, and even if their boundary faces are coincident, a separate face will exist to bound each solid. Non-manifold representations extend the concept of manifold to represent the wider range of configurations needed for analysis. Consequently, an edge can be adjacent to more than two faces, a face can be shared by two solids. For example, a solid composed of two different materials, or a structural model with multiple shell bodies attached at an edge. A non-manifold geometric modelling kernel also incorporates the ability to describe and connect geometric regions of different manifold dimensions. Most of the commercial FEA packages contain manifold geometric modellers with extensions to be able to model non-manifold objects.
