Research On The Visualization Techniques For The Optimum Modeling Of Antenna Structures

The optimization for antenna structures turns to be more important for its complexity and high precision. Illustrated by antennas' structure optimization, it ispresented the three essential modules——geometry module, FEM module,optimizations module, which build visualization software systems of structure optimizations.This paper applies visualization in scientific computing (VISC) to design optimizationg of antenna. And the construction of a human-computer interface based on the integration of softwares can advance the application of optimization design to engineering.This paper determines the design idea of combining antenna design and VISC based on the general design scheme on virtual manufacturing system. A visualization environment is developed, in which the objective function, constraint functions and the design variables can be determined conveniently through human-computer interface. Three points are put forward: functional moules design, I/O design between block and extrinsic form. Content and implementation scheme of VISC software platform are researched, and the gradation structure of software is partitioned and described. Some key techniques are presented, and the emphasis is visual design variable merging through the practical application of the technique for opening I-DEAS software, and calling and controlling of calculation program written in Fortran in the development environment of Delphi are in virtue of the techniques of Fortran/Delphi mixed-language programming. In the end, functional modules have been integrated and a typical computational example on antenna structure is verified.
