The contest in comsol is PDE mode, general form, in 1D space dimension, let u(x,t) be one of the independent variables and f(t) a known function of my problem. What I want to implement in the F term of the field equation ea*du^2/dt^2+da*du/dt+div(G)=F is F= int_0^...
where gauTF is a gaussian transfer function for the convolution (sigma is a parameter and u is the desired value. since everything eles in the general form PDE is 0 Comsol solves the problem. Then I introduce a 2D cutline and take the convoluted data. However the data on the rest of t...
(ABC) to truncate unbounded media.In this paper,the CPML equations have been presented in frequency domain and in time domain,respectively,and the calculations have been realized in the FEM software of COMSOL.The main advantage of CPML over the classical PML layer is that it is based on the...
To validate the proposed methods, datasets are created with COMSOL Multiphysics and Matlab.The mean error range of 100鈥 2 000 Hz of the algorithm proposed in this paper is only 4.96%, higher than those of SRCNN and PV-NN.The proposed method is verified as having the potential to ...
在这份报纸, CPML 方程在频率领域并且及时被介绍了领域,分别地并且计算在 COMSOL 的女性的软件被认识到.在古典 PML 层上的 CPML 的主要优点是它基于导致更稳定的,高度有效的吸收和一台更多的设备认识到的波浪地的 unsplit 部件.数字模拟的结果证明 CPML 比 PML 有更好的被吸收,它吸收 out~oin~ 精力更多的 ...
