Parallel Finite Element Subdivision Method for Electromagnetic Analysis of a Large Interior Space

Abstract

In high-frequency electromagnetic field analysis, it is necessary to divide the waveform into elements whose maximum side length is 1/10 to 1/20 of the wavelength so that the waveform can be expressed with low error when a space is divided. Therefore, in many cases, it becomes a largescale problem. In this study, due to the need for electromagnetic compatibility (EMC) evaluation of the surrounding electromagnetic field generated when a microwave scalpel is used in surgery, a large-scale electromagnetic analysis method for the microwave region inside the operating room has been developed. In this paper, the introduced parallel mesh subdivision function enables highspeed mesh generation with hundreds of millions of elements. In addition, this method provided a successful analysis.
