FDTD fails to end simulation properly with FDE error
At the end of FDTD simulation, .fsp file is saved with data loaded into fields, however simulation window freezes. It happens for small and large .fsp end of sim file sizes. If window is now forcibly closed, attached warning comes up. The only way to open a completed .fsp simulation is thus by closing it forcibly, and then re-opening. Without checking file sizes, it is not obvious that simulation has completed successfully.
