Datenstrukturen zur Koerpermodellierung und Netzmodellierung

This work describes data structures for the integrated modeling of solids and finite element meshes. Different boundary representation schemes are applied to describe the complex topological and geometrical structures. The solid modeler uses the radial edge data structure, which is significantly improved by the object-oriented programming. The new mesh model consists of a B-Rep- and a FE-Structure. This hybrid mesh data structure describes complex topological forms and finite element meshes simultaneously. The time efficiency and the storage requirement of the mesh data structure is demonstrated. The attributes of a particular physical problem are defined separately of the CAD-FEM-System. A protocol controls the association between the integrated system and the physical attributes.
