Abstract: In many engineering applications in the area of field computation, the numerical models are based on the finite element method (FEM). The FEM programs have a modular form in accordance the stages of the method: pre-processing, solution (processing) and postprocessing. The greatest task in any finite element program is generally the preparation of the input data. There is a large amount of input data that consists in both geometrical and physical data.
Our work concerned to pre-processing of the FEM programs. In order to eliminate much of the effort involved in data preparation for finite element programs, an automatic or semi-automatic mesh generation can be employed. In this way the data errors which inevitably occur during manual preparation are eliminated.
There are a lot of methods for mesh generation and adaptive mesh. We present some algorithms for for the software products in the area CAD based on the finite element method with a special interest for the decomposition method for the mesh generation. This interest is generated by the advanced computer architectures.
