Export time domain data from OptiFDTD analyzer
I am currently using the Free 32bit version of OptiFDTD and would like to generate a video showing the time domain evolution of the simulated fields. While the simulation is running, this information is nicely displayed, yet, I did not find a way to store it properly.
I already tried the following approach:
Generate an observation plane which covers my region of interest and save the field components I like.
After running the simulation, in OptiFDTD analyzer I go to Tools -> Observation Area Analysis and then click Spectrum Analysis in the window that opens. When selecting the radio button for Time domain (fs), I can verify that for each point in the observation plane, the time data was actually stored correctly.
Finally, in the Observation Area Analysis window, I click Export Data and select a Time domain field component. However, the resulting .f3d file only contains the first frame of the simulation.
Could anyone please help me solve this issue? Any advice is appreciated!
