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.

 

!----------------------------------------------------------!
$current-cluster                                 optional  !
 cluster-number               integer            required  !
 region-numbers               integer_array      required  !
 deactivate-cluster           character          optional  !
$end_current-cluster                             optional  !
!--------------------------------------------------------- !

 

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.
