::TD Output
<br/><i>Type</i>: flag
<br/><i>Default</i>: multipoles + geometry + temperature + energy
<br/><br> Defines what should be output during the time-dependent simulation.

<br/><i>Options</i>:
<ul>
<li><b>gauge_field</b>:  If set, outputs the vector gauge field corresponding to a spatially uniform (but time-dependent)
 external electrical potential. This is only useful in a time-dependent periodic run.
</li>
<li><b>energy</b>:  If <tt>set</tt>, <tt>octopus</tt> outputs the different components of th
