I had the program output the time for every step and noticed the time was increasing by 1/6 even though the resolution was set to 3. Is that a problem with the time that can be corrected by multiplying the output time by 2 or is it a problem with the resolution that can be corrected by multiplying the resolution by 0.5?
As explained in the MEEP introduction, FDTD is governed by the Courant stability criteria \delta t = S \delta x (where the speed of light is taken to be unity). Hence, the temporal resolution is governed by the spatial resolution as you have discovered. Only the spatial resolution and S (by default 0.5) can be altered in MEEP.
