Detailed Description

template<typename System, typename BackgroundTag, size_t Dim = System::volume_dim>
struct elliptic::Actions::InitializeFixedSources< System, BackgroundTag, Dim >

Initialize the "fixed sources" of the elliptic equations, i.e. their variable-independent source term \(f(x)\).

This action initializes \(f(x)\) in an elliptic system of PDEs \(-div(F) + S = f(x)\).
