NewtonianEuler::subcell Namespace Reference

Code required by the DG-subcell/FD hybrid solver. More...

## Classes

struct  DgInitialDataTci
The troubled-cell indicator run on DG initial data to see if we need to switch to subcell. More...

struct  NeighborPackagedData
On elements using DG, reconstructs the interface data from a neighboring element doing subcell. More...

class  PrimitiveGhostDataOnSubcells
Computes the mass density, velocity, and pressure on the subcells so they can be sent to the neighbors for their reconstructions. More...

class  PrimitiveGhostDataToSlice
Projects the mass density, velocity, and pressure to the subcells so they can be sent to the neighbors for their reconstructions. More...

struct  PrimsAfterRollback
Mutator that resizes the primitive variables to the subcell mesh and computes the primitives, but only if evolution::dg::subcell::Tags::DidRollback is true. More...

struct  ResizeAndComputePrims
Mutator that resizes the primitive variables to have the size of the active mesh and then computes the primitive variables on the active mesh. More...

struct  SetInitialRdmpData
Sets the initial RDMP data. More...

class  TciOnDgGrid
Troubled-cell indicator applied to the DG solution. More...

class  TciOnFdGrid
Troubled-cell indicator applied to the finite difference subcell solution to check if the corresponding DG solution is admissible. More...

struct  TimeDerivative
Compute the time derivative on the subcell grid using FD reconstruction. More...

## Functions

template<size_t Dim, typename TagsList >
void compute_fluxes (const gsl::not_null< Variables< TagsList > * > vars)
Helper function that calls ComputeFluxes by retrieving the return and argument tags from vars.
