Paper Abstract

A thorough analysis reveals that the approximation theory has various applications in the computer aided engineering. The early ideas about approximation and spline functions were related to the graphical aspects in the general design of a motor vehicle1. Since then, the ideas evolved together with the tremendous progress of the computer science which offered software platforms with advanced numerical methods’ solvers. Beside the original computer instruments we developed, a far better idea is to gather ‘la crème de la crème’, the best of the best software concepts and solutions in a unique strategy of development. This meta-level of understanding and integration is useful for the rapid development of computer based hybrid models to be used in complex research problems. We consequently selected GNU OCTAVE as a scientific programming platform which might provide the solutions (in various forms) of the interpolation problems using spline functions. The initial solution4 was constantly upgraded with respect to the context of the case studies to be solved. After 98 interpolation problems solved over 5 years, new important facilities were added to the initial software solution. The main directions are: generalization of the program which should not include case studies dedicated sequences (no hard coded sequences), several and more reliable links to upper level applications and new facilities used to control the aspect of the graphical output because the visual control may evaluate the output data in a more effective way than the mathematical/technical conditions. The upgraded version of the software may be considered a milestone in the progress of the ‘general modeling original platform development’ concept9.
