Detailed Description

template<typename DirectionsTag, typename Tag>
struct domain::Tags::Slice< DirectionsTag, Tag >

Compute tag for representing a compute item that slices data from the volume to a set of interfaces.

The computed object will be a map from a Direction to the item type of Tag (i.e. Tag::type), with the set of directions being those produced by DirectionsTag. Tag::type must be a Tensor or a Variables. Retrievable from the DataBox using Tags::Interface<DirectionsTag, Tag>

Requires: Tag correspond to a Tensor or a Variables

Template Parameters
DirectionsTagthe simple tag labeling the set of Directions
Tagthe simple tag for the volume data to be sliced
