Detailed Description

template<typename System>
struct Initialization::Actions::NonconservativeSystem< System >

Allocate variables needed for evolution of nonconservative systems.

Uses:

• DataBox:
  • Tags::Mesh<Dim>

DataBox changes:

• Adds:
  • System::variables_tag
  • Tags::Variables<System::auxiliary_variables> (only if the system declares a non-empty auxiliary_variables)
• Removes: nothing
• Modifies: nothing
