Instrumental data preparation and analysis software for solution of 3d mathematical physics problems

The approach to development of specialized problem-oriented 3D pre- and post-processors for finite element analysis is proposed. Structure and components of the instrumental software are considered. The base geometric model for the instrumental tools is constructed using the theory of topological complexes and their transformations. The applications of the developed software to modelling of arbitrary geometrical shapes, unstructured grids, finite elements as well as representation of numerical results are described.
