-fdtd/-voltages: Voltage sources between selected points

During a time domain computation (with a static mesh, ie. not windowwake), voltages along paths can be specified and measured.

• startpoint, endpoint:
  Startpoint and endpoint of the path. The voltage is applied between these two points.
• resistance:
  Inner resistance of the voltage source.
• amplitude, phase, frequency, bandwidth:
  The amplitude, phase, centerfrequency and bandwidth of the voltage source.
• risetime:
  If specified nonzero, the voltage source is switched on. The risetime of the voltage
• logcurrent:
  Whether the current through the voltage source shall be monitored.
• name:
  The name of the voltage source.

If voltage sources are specified, the electric field strength between the startpoint and endpoint are measured while the time domain computation is running. The difference between the specified voltage and the so measured voltage is multplied by the resistance of the voltage source. That value is used as current which is enforced to flow between the startoing point and endpoint.

The values of the wanted voltage, the measured voltage and the current can be inspected in the postprocessor.
