matlab_FEM_dismesh
DistMesh giving a singular FEM matrix?(Hi
Anyone here with some experience of using DistMesh in finite element code? I m solving the scalar Helmoltz equation in an annular region in 2D:
rho_1 < rho < rho_2
where rho_1 is the radius of a Perfect Electric Conducting cylinder and rho_2 is where the mesh is truncated using an Absorbing Boundary condition.
Now, I ve written code to mesh the region myself (by dividing the region into annular rings and picking a fixed number of points on each ring) and I ve written another program which uses DistMesh to mesh the region. I get a nice solution using my own meshing code but the FEM matrix becomes singular when I use DistMesh. This is the DistMesh Code I used:
Circle with hole
rABC=1.5
rCyl=0.5
fdstring=sprintf( ddiff(dcircle(p,0,0, f),dcircle(p,0,0, f)) ,rABC,rCyl)
fd=inline(fdstring, p )
box=[-2,-2 2,2]
[p,N]=distmesh2d(fd,@huniform,0.04,box,[])
I tried changing box and the 0.04 value (initial edge length). But every time, the matrix becomes sin)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)
