Strange Results with Large Geometry about py-tdgl HOT 3 CLOSED

I think this is related to your other question (#31) about time-dependent applied vector potential. It is unphysical for the applied field to go from zero to some large value instantaneously, which is effectively what happens in the first time step of the simulation. Above a certain value of the applied field, this results in vortices nucleating in the bulk, which I think is not true to reality as you said. If you were to instead ramp the applied field up from zero over some amount of time, I believe all vortices would come from the edges. I will think about how to add time-dependent applied fields - one subtlety is that there is an additional electric field term proportional to dB/dt that needs to be included. As you pointed out in the other GH issue, you can effectively ramp up the applied field by seeding a simulation with the results of a previous one, but this is cumbersome.

I am going to close this issue because I have merged #33, which adds support for time-dependent vector potentials
