Detailed Description

template<typename DataType, size_t Dim, typename Frame>
struct gh::Tags::InitialGaugeH< DataType, Dim, Frame >

Initial value of the gauge source function for the generalized harmonic system.

Details

In the generalized / damped harmonic gauge, unlike the simple harmonic gauge, the right hand side of the gauge equation \( \square x_a = H_a\) is sourced by non-vanishing functions. This variable stores the initial or starting value of those functions \( H_a\), which are set by the user (based on the choice of initial data) to begin evolution.
