Tasks Manager

The GEOSX tasks manager allows a user to specify tasks to be executed. These tasks are compatible targets for the EventManager.

The tasks manager is configured via the Tasks block in an input .xml file, i.e.:

<Tasks>
  <PackCollection name="historyCollection" objectPath="nodeManager" fieldName="Velocity" />
</Tasks>

Tasks Manager Configuration

Task

The children of the Tasks block define different Tasks to be triggered by events specified in the EventManager during the execution of the simulation. At present the only supported task is the PackCollection used to collect time history data for output by a TimeHistory output.

PackCollection

The PackCollection Task is used to collect time history information from fields. Either the entire field or specified named sets of indices in the field can be collected.

Note: The time history information collected via this task is buffered internally until it is output by a linked TimeHistory Output.

Triggering the Tasks

Tasks can be triggered using the EventManager. Recurring tasks sould use a <PeriodicEvent> and one-time tasks should use a `<SoloEvent>`:

<PeriodicEvent name="historyCollectEvent"
               timeFrequency="1.0"
               targetExactTimeset="1"
               target="/Tasks/historyCollection" />

The keyword target has to match the name of a Task specified as a child of the <Tasks> block.
