Detailed Description

template<size_t Dim, typename GhostDataMutator, bool UseNodegroupDgElements>
struct evolution::dg::subcell::Actions::SendDataForReconstruction< Dim, GhostDataMutator, UseNodegroupDgElements >

Sets the local data from the relaxed discrete maximum principle troubled-cell indicator and sends ghost zone data to neighboring elements.

The action proceeds as follows:

1. Determine in which directions we have neighbors
2. Slice the variables provided by GhostDataMutator to send to our neighbors for ghost zones
3. Send the ghost zone data, appending the max/min for the TCI at the end of the DataVector we are sending.

Warning

This assumes the RDMP TCI data in the DataBox has been set, it does not calculate it automatically. The reason is this way we can only calculate the RDMP data when it's needed since computing it can be pretty expensive.

Some notes:

• In the future we will need to send the cell-centered fluxes to do high-order FD without additional reconstruction being necessary.

GlobalCache:

• Uses:
  • ParallelComponent proxy

DataBox:

• Uses:
  • domain::Tags::Mesh<Dim>
  • subcell::Tags::Mesh<Dim>
  • domain::Tags::Element<Dim>
  • Tags::TimeStepId
  • Tags::Next<Tags::TimeStepId>
  • subcell::Tags::ActiveGrid
  • System::variables_tag
  • subcell::Tags::DataForRdmpTci
• Adds: nothing
• Removes: nothing
• Modifies:
  • subcell::Tags::GhostDataForReconstruction<Dim>
