Detailed Description

Used by LOCA::Epetra::Group to provide a link to the external code for the MassMatrix (coefficients of time dependent terms).

This is used for Hopf bifurcation tracking, linear stability analysis, and space-time solutions (xyzt).

	)

Provides data to application for output files.

This routine is called from Interface::xyzt::printSolution() just before the call to Interface::Required::printSolution(x,param), and gives the application some indices that can be used for creating a unique name/index for the output files.

virtual void LOCA::Epetra::Interface::MassMatrix::setOldSolution	(	const Epetra_Vector &	x,
		const int	timeStep
	)

inlinevirtual

Routines used in XYZT to set the old solution, the one from the previous time step.

There is a different routine for first step, where the old solution is set by the user and not part of the solution vector. These routines are used by space-time (xyzt) problems, where the residual vector is a function of the previous solution, which is also being solved for, and where the MassMatrix is calculated as a function of a different solution vector then the Jacobian (that is, the previous time step). The timeStep argument is sent so the use can set the global time, for cases when computeF, computeJacobian, computeMassMatrix fills are functions of time (nonautonomous systems).
