Detailed Description

template<typename System, typename BackgroundTag>
struct elliptic::Actions::InitializeFixedSources< System, BackgroundTag >

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 \(-div(F) + S = f(x)\).

Uses:

• System:
  • primal_fields
• DataBox:
  • BackgroundTag
  • Tags::Coordinates<Dim, Frame::Inertial>

DataBox:

• Adds:
  • db::wrap_tags_in<Tags::FixedSource, primal_fields>

Note

This action relies on the SetupDataBox aggregated initialization mechanism, so Actions::SetupDataBox must be present in the Initialization phase action list prior to this action.
