下面我们将使用Python和Numpy库来实现一个简单的2D FDTD仿真。在这个示例中,我们将模拟一个无源、非色散的媒质中的电磁波传播。首先,确保您已经安装了Python和Numpy库。如果尚未安装,请通过pip进行安装: pip install numpy 接下来,创建一个Python文件(例如:fdtd_simulation.py),然后编写以下代码:```pythonimport numpy...
fdtd.select("FDTD") fdtd.set('simulation time',8e-12) 设置仿真时间为8飞秒 设置时间步长稳定因子 fdtd.set('dt stability factor',0.99) 相当于设置了时间步长dt 设置密集网格区域 #加入mesh区域 fdtd.addmesh() fdtd.set('x min',x_min) fdtd.set('x max',x_max) fdtd.set('z',z) fdtd.set...
```python import fdtd import numpy as np # 设置模拟参数 nx, ny, nz = 100, 100, 100 dx, dy, dz = 0.01, 0.01, 0.01 dt = 0.01 # 创建模拟对象 sim = fdtd.Simulation(nx, ny, nz, dx, dy, dz, dt) # 设置边界条件 sim.set_boundary_conditions(fdtd.BC_PERIODIC, fdtd.BC_PERIODIC, ...

Running a simulation is as simple as using thegrid.runmethod. grid.run(total_time:Number,progress_bar:bool=True) Just like for the lengths in the grid, thetotal_timeof the simulation can be specified as an integer (number oftime_steps) or as a float (in seconds). ...
我用perl和python写了相同功能的一段程序,计算一维fdtd,用gnuplot动态显示,可是python的数据没有显示出来,看横纵坐标的变化数据是正确收到了的,如最后的图片,求大神指点,谢谢。 1#!/usr/bin/perl23# Author : Leon Email: yangli0534@gmail.com4# fdtd simulation , plotting with gnuplot, writting in perl5...
