Detailed Description

template<size_t VolumeDim, typename ObservationValueTag, typename... Tensors, typename... NonTensorComputeTags, typename ArraySectionIdTag>
class dg::Events::ObserveVolumeIntegrals< VolumeDim, ObservationValueTag, tmpl::list< Tensors... >, tmpl::list< NonTensorComputeTags... >, ArraySectionIdTag >

Observe the volume integrals of the tensors over the domain.

Writes reduction quantities:

• ObservationValueTag
• Volume = volume of the domain
• VolumeIntegral(*) = volume integral of the tensor

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.
