Detailed Description

template<size_t Dim>
struct evolution::dg::BoundaryData< Dim >

The data communicated between neighber elements.

The stored data consists of the following:

  1. the volume mesh of the element.
  2. the volume mesh corresponding to the ghost cell data. This allows eliding projection when all neighboring elements are doing DG.
  3. the mortar mesh of the data on the mortar
  4. the variables at the ghost zone cells for finite difference/volume reconstruction
  5. the data on the mortar needed for computing the boundary corrections (e.g. fluxes, characteristic speeds, conserved variables)
  6. the TimeStepId beyond which the boundary terms are no longer valid, when using local time stepping.
  7. the troubled cell indicator status used for determining halos around troubled cells.
  8. the integration order of the time-stepper
  9. the InterpolatedBoundaryData sent by a non-conforming Element that interpolates its data to a subset of the points of the Element receiving this BoundaryData
