Automatic mesh generation and finite element analysis of a triax dome

An overview of automatic mesh generation is presented and the need for a specialized mesh generation program for triax domes is discussed. The method of generation of the triax dome geometry, the terminology, the dome members and loading conditions and its modelling with ABAQUS is explained briefly. Development of an automatic mesh generation program, its structure and functions, the limitations and desirable extensions are also discussed. The program generates nodal coordinate and element connectivity data and also has mesh refinement features. All the necessary data required for modelling the triax dome with ABAQUS is generated automatically by the program. The model of an existing triax dome at Raleigh, North Carolina, is generated by the mesh generation program and is analyzed for stresses and displacements using the ABAQUS finite element analysis program.
