## Detailed Description

template<size_t Dim>
struct evolution::dg::subcell::fd::Tags::InverseJacobianLogicalToGrid< Dim >

The inverse Jacobian from the element logical frame to the grid frame at the cell centers.

Specifically, $$\partial x^{\bar{i}} / \partial x^i$$, where $$\bar{i}$$ denotes the element logical frame and $$i$$ denotes the grid frame.

Note
stored as a std::optional so we can reset it when switching to DG and reduce the memory footprint.
