Electrically Large Structures in WIPL-D

Abstract

In this paper, an electrically large structure, a 50-lambda (where lambda is the wave length) long airplane and a dual-polarized 60-element Vivaldi array are run in 64-bit version WIPL-D software on the Intel Itanium2 platform with 64GB physical memory. The scattering electromagnetic parameters (the RCS, the surface current, and the near field) and the radiation pattern are shown. The memory usage and the CPU times for different number of unknowns larger than the limit of 32-bit PCs are listed. We also show that this 64-bit version of WIPL-D can go beyond the 64GB physical memory and the speed is not significantly decreased when the virtual memory is used.
