Simulation – Nalu Top-level Interface
Realms
Realm is a Nalu abstraction of a set of equations that are solved on a
computational domain, reresented by an Exodus-II mesh. A simulation can contain
multiple Realms and that can interact via sierra::nalu::Transfer
instance. sierra::nalu::InputOutputRealm is a special type of Realm
that exists solely to provide data (input) or extract a subset of data from
another sierra::nalu::Realm.
