Detailed Description

template<Xcts::Equations EnabledEquations>
class Xcts::BoundaryConditions::Flatness< EnabledEquations >

Impose flat spacetime at this boundary.

Impose \(\psi=1\), \(\alpha\psi=1\), \(\beta_\mathrm{excess}^i=0\) on this boundary, where \(\psi\) is the conformal factor, \(\alpha\) is the lapse and \(\beta_\mathrm{excess}^i=\beta^i-\beta_\mathrm{background}^i\) is the shift excess (see Xcts::Tags::ShiftExcess for details on the split of the shift in background and excess). Note that this choice only truly represents flatness if the conformal background metric is flat.

Template Parameters

EnabledEquations The subset of XCTS equations that are being solved
