Detailed Description

template<class AllSolutionsForChristoffelAnalytic, size_t Dim>
struct gh::gauges::SetPiAndPhiFromConstraints< AllSolutionsForChristoffelAnalytic, Dim >

Set \(\Pi_{ab}\) from the gauge source function (or 1-index constraint) and \(\Phi_{iab}\) from the 3-index constraint.

This is necessary to ensure the initial data is in the desired evolution gauge and that the 1- and 3-index constraints are satisfied.
