Detailed Description

template<size_t Dim>
class NewtonianEuler::subcell::TciOnDgGrid< Dim >

Troubled-cell indicator applied to the DG solution.

Computes the primitive variables on the DG grid, mutating them in the DataBox. Then,

• apply RDMP TCI to the mass and energy density
• if the minimum density or pressure are below \(10^{-18}\) (the arbitrary threshold used to signal "negative" density and pressure), marks the element as troubled and returns
• runs the Persson TCI on the mass and energy density. The reason for applying the Persson TCI to both the mass and energy density is to flag cells at contact discontinuities.
