discrete_alloc function, argument 6: AtomicRegions

definition

AtomicRegions is the sixth argument of the discrete_alloc function.

AtomicRegions is a domain unit defining the set of atomic regions.

It contains attributes for each PartioningAttribute that define to which region each atomic region belongs for that PartioningAttribute.

description

The overlay function is used to derive an AtomicRegions unit with the set of relevant subitems for the discrete_alloc function, see the example.

applies to

unit AtomicRegions with value types:

uint8 or
uint16

conditions

The names of the regions (subitems of the third argument of the overlay function) need to match with the values of the PartioningName argument.

example

unit<uint8> lu_type: nrofrows = 3
{ 
   attribute<string> PartioningName: ['Living','Working','Nature'];
}
container regionSets
{
   attribute<regMaps/p1> Nature  (DomainGrid) := regMaps/p1Map;
   attribute<regMaps/p1> Living  (DomainGrid) := regMaps/p1Map;
   attribute<regMaps/p2> Working (DomainGrid) := regMaps/p2Map;
}
unit<uint16> AtomicRegions := overlay(lu_type/PartioningName, DomainGrid, regionSets);
