Optimization of the Cut-cell Mesh-Generating Code for Simulation of Vacuum Electronic Devices

A cut-cell mesh-generating code was developed and optimized to simulate vacuum electronic devices. This code can provide the needed Cut-cell mesh when simulating vacuum devices by conformal Finite Differential Time Domain (FDTD) method. This article was focused on the efficiency improvement of the Cut-cell mesh-generation code. The test results show that the meshing efficiency is greatly improved while maintaining the certain computational accuracy.
