Analytic solutions Graphics Important modifications Installation and running MMP solver New features PFD solver System requirements
PFD is a Predefined FD solver that currently is implemented only for dynamic 2D and 3D scattering problems based on a standard leap-frog scheme. These solvers have the following features:
2D and 3D FDTD schemes
complex FDTD schemes for periodic structures (e.g. gratings with arbitrary angle of incidence)
First order Drude-Lorentz models for dispersive materials
UPML, PEC, PMC, and periodic boundary conditions
Plane wave, point soures, and MMP expansion sources
MMP based near-to-far field transformation
Discrete Fourier analysis for complex field representation in the frequency domain and easy comparison with MMP results
Sensor points with discrete Fourier analysis of the frequency dependence of the field in the sensor points
For using PFD, you specify the number of Iterations, the desired Time step, the PFD grid, absorbing layers, excitation, sensor points, , etc. in the PFD dialog.
Note that PFD uses a regular grid that may be different from the OpenMaXwell field grid that is used for drawing the field in the graphics window.
Since PFD is currently under construction, no detailed information is given here.
