Detailed Description

template<class T>
class TGAHelmOp< T >

This operator is meant to represent the general helmholtz operator that AMRTGA will be solving. This operator is of the form alpha A(x) phi + beta div B(x) grad phi = rho. AMRTGA needs to reset the constants alpha and beta often.

Member Function Documentation

template<class T>

virtual void TGAHelmOp< T >::setAlphaAndBeta	(	const Real &	a_alpha,
		const Real &	a_beta
	)			[pure virtual]

set the constants in the equation

Implemented in AMRPoissonOp, ResistivityOp, VCAMRPoissonOp, VCAMRPoissonOp2, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, and EBViscousTensorOp.

Referenced by AMRTGA< T >::resetAlphaAndBeta(), and BaseLevelTGA< T, TFlux, TFR >::resetSolverAlphaAndBeta().

template<class T>

virtual void TGAHelmOp< T >::diagonalScale

(

T &

a_rhs

)

[pure virtual]

Set the diagonal scaling of the operator. If you are solving rho(x) dphi/dt = L(phi), this would mean multiply by rho. In EB applications, even for constant coefficients, it means to multiply by kappa.

Implemented in AMRPoissonOp, ResistivityOp, VCAMRPoissonOp, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, and EBViscousTensorOp.

template<class T>

virtual void TGAHelmOp< T >::applyOpNoBoundary	(	T &	a_ans,
		const T &	a_phi
	)			[pure virtual]

apply operator without any boundary or coarse-fine boundary conditions and no finer level

Implemented in AMRPoissonOp, ResistivityOp, VCAMRPoissonOp, VCAMRPoissonOp2, ViscousTensorOp, EBAMRPoissonOp, EBConductivityOp, and EBViscousTensorOp.
