grmhd::GhValenciaDivClean::subcell::PrimitiveGhostVariables Class Reference

Computes the rest mass density $\rho$, electron fraction $Y_e$, pressure $p$, Lorentz factor times the spatial velocity $W{v}^i$, magnetic field $B^i$, the divergence cleaning field $\mathrm{\Phi }$, and the generalized harmonic evolved variables $g_{ab}$, ${\mathrm{\Phi }}_{iab}$ and ${\mathrm{\Pi }}_{ab}$ on the subcells so they can be used for reconstruction.

Detailed Description

Computes the rest mass density $\rho$, electron fraction $Y_e$, pressure $p$, Lorentz factor times the spatial velocity $W{v}^i$, magnetic field $B^i$, the divergence cleaning field $\mathrm{\Phi }$, and the generalized harmonic evolved variables $g_{ab}$, ${\mathrm{\Phi }}_{iab}$ and ${\mathrm{\Pi }}_{ab}$ on the subcells so they can be used for reconstruction.

The computation copies the data from the primitive variables to a new Variables and computes $W{v}^i$. In the future we will likely want to elide this copy but that requires support from the actions.

This mutator is passed to evolution::dg::subcell::Actions::SendDataForReconstruction.

Only called on elements using FD.
