Current-cluster
For current calculations, you have to define current regions ($current-regions) and
current clusters
on which certain current models ($current-models) are applied.
As for the regions and quantum-regions, current-regions can be clustered. At least cluster number 1 has to be specified
if the current has to be calculated at all.
The syntax of the region-cluster, quantum-cluster, and current-cluster is
very similar.
For more info on specifiers see $region-cluster,
$quantum-cluster.

cluster-number =
1
an integer number to refer to geometry element
region-numbers =
1
region numbers, belonging to cluster
deactivate-cluster = yes
= no
Flag to switch off current clusters (yes|Yes|YES).
Anything else means NO (default).
Switching off current calculation means equilibrium simulation.
This is a very convenient way to turn the current calculation off and on.
