Estimation of simulation time and nyquist rate for the simulation

Post by bonkoung2 » Tue 19 Jul 2022, 14:37

Hello,
I am beginner with openems. An I asked myself a lot of questions.
Is someone know how to estimate the time of simution and the nyquist rate during the simulation?

Create FDTD operator (compressed SSE + multi-threading)
FDTD simulation size: 78x58x37 --> 167388 FDTD cells
FDTD timestep is: 2.72361e-14 s; Nyquist rate: 5321 timesteps @3.45011e+09 Hz
openEMS::SetupFDTD: Warning, the timestep seems to be very small --> long simulation. Check your mesh!?
Excitation signal length is: 105184 timesteps (2.8648e-09s)
Max. number of timesteps: 300000 ( --> 2.85214 * Excitation signal length)
openEMS::SetupFDTD: Warning, max. number of timesteps is smaller than three times the excitation.
You may want to choose a higher number of max. timesteps...
Create FDTD engine (compressed SSE + multi-threading)
