Detailed Description

The base class PatchGodunov provides an implementation of a second-order, unsplit Godunov method acting on a single grid/patch. PatchGodunov provides an interface to the level integrator, LevelGodunov, which manages the entire level and flux corrections (via flux registers) to the coarser and finer levels.

	)

virtual

Compute the time-centered values of the primitive variables on cell faces.

This API is used in cases where some operation over the whole level must be performed on the face-centered variables prior to the final difference update. Examples include incompressible flow and MHD, in which it is necessary to compute the projection of a face-centered vector field on its divergence-free part. To complete the differencing, it is necessary to call the member function computeUpdate().

Parameters

a_WHalf	primitive variables extrapolated to cell faces and a half time step
a_U	conserved variables at beginning of time step
a_S	source terms, or null constructed if none
a_dt	time step
a_box	Box of a_U

		const Box &	a_box
	)

virtual

Compute the increment in the conserved variables from face variables.

Compute dU = dt*dU/dt, the change in the conserved variables over the time step. The fluxes are returned are suitable for use in refluxing.
