Detailed Description

template<typename T>
class tensorium_RG::BSSN< T >

Driver class to initialize and store BSSN variables from an input spacetime metric.

This class initializes all core variables required for BSSN evolution using a given spacetime metric. The metric must provide access to the lapse, shift, and spatial metric via metric.BSSN(X, α, β^i, γ_ij).

Template Parameters
TNumeric type (e.g. double)
