In this paper , we will introduce an accurate and stable method which bases on mot to solve dielectric objects and metal - nonmetal composite objects 在本文文章中,介紹了一種基于時(shí)間步進(jìn)法求解介質(zhì)目標(biāo)、金屬非金屬組合目標(biāo)時(shí)域積分方程的精確,穩(wěn)定的方法。
Because of the large advantage in the analysis of electromagnetic scattering and radiation problem , using the time domain integral equation ( tdie ) solving every structure of objects ’ scattering become to an important direction in computation electromagnetics , but the classical mot ( marching - on - in - time ) - based tdie solvers have a drawback : the late time stability problems 由于時(shí)域積分方程對(duì)于分析電磁散射、輻射問(wèn)題有著無(wú)可比擬的優(yōu)勢(shì),利用時(shí)域積分方程求解各種結(jié)構(gòu)體目標(biāo)散射成為計(jì)算電磁學(xué)領(lǐng)域中一個(gè)非常重要的方向。但是傳統(tǒng)的時(shí)間步進(jìn)法求解時(shí)域積分方程存在致命缺點(diǎn):后時(shí)穩(wěn)定性不好。
By means of c - language , the paper has developed a large - scale computer program , in which the combination of both the newton iteration and the gradient method is introduced to solve reynolds equation and film thickness equation , and the march method is used to solve the energy equation and heat interface equations , the satisfactory results are obtained 本文采用c語(yǔ)言編制了大型計(jì)算機(jī)程序進(jìn)行數(shù)值計(jì)算,數(shù)值計(jì)算中采用梯度-牛頓聯(lián)合法求解reynolds方程和油膜厚度方程,采用步進(jìn)法求解能量方程和熱界面方程,獲得了滿意的數(shù)值結(jié)果。
