Detailed Description

template<typename ObservableTensorTagsList, typename NonTensorComputeTagsList = tmpl::list<>, typename ArraySectionIdTag = void>
class Events::ObserveAtExtremum< ObservableTensorTagsList, NonTensorComputeTagsList, ArraySectionIdTag >

Find the extremum of a Scalar<DataVector> over all elements, as well as the value of other functions at the location of that extremum.

Here is an example of an input file:

      R"(
  ObserveAtExtremum:
    SubfileName: reduction0
    TensorsToObserve:
      Name: Var0
      ExtremumType: Max
      AdditionalData:
      - Var0
      - Var1
        )");

Array sections: This event supports sections (see Parallel::Section). Set the ArraySectionIdTag template parameter to split up observations into subsets of elements. The observers::Tags::ObservationKey<ArraySectionIdTag> must be available in the DataBox. It identifies the section and is used as a suffix for the path in the output file.

The documentation for this class was generated from the following file:
