The purpose of this study is to construct a intuitive design support system using virtual reality. We constructed the design support system which displays objects by CG (computer graphics) and calculates the interference among these objects at high speed and high accuracy. Finally this system provides users pseudo force corresponding the amount of the interference.We applied this system to not only the interference among objects, but also representation of electromagnetic field distribution. The method of representing electromagnetic field has not been researched, therefore we applied force representation to observe in local phenomena.Further, we developed numerical simulation code of electromagnetic field by Finite-difference time-domain method for the proposed system.

这项研究的目的是使用虚拟现实构建直观的设计支持系统。我们构建了设计支持系统，该系统通过CG（计算机图形）显示对象，并以高速和高精度计算这些对象之间的干扰。最后，该系统为用户提供了伪力，使干扰量相对应。我们不仅将该系统应用于对象之间的干扰，而且还代表电磁场分布。尚未研究代表电磁场的方法，因此我们应用了力代表来观察局部现象。库尔特，我们通过有限差分差异时间域方法为所提出的系统开发了电磁场的数值模拟代码。
