virtual void NWOViscousTensorOp::diagonalScale ( LevelData< FArrayBox > &  a_rhs,
bool  a_kappaWeighted 
)
inlinevirtual

Scales the right hand side of the Helmholtz equation by the identity term in the operator. If you are solving rho(x) dphi/dt = L(phi), this means multiply by rho (or kappa * rho in embedded boundary calculations.

Parameters
a_rhsThe right hand side of the equation to be scaled.
a_kappaWeightedIf set to true, a_rhs will be scaled by the volume fraction in addition to the identity term.

Reimplemented from TGAHelmOp< LevelData< FArrayBox > >.

virtual void NWOViscousTensorOp::setAlphaAndBeta ( const Real a_alpha,
const Real a_beta 
)
inlinevirtual

Sets the scaling constants in the Helmholtz equation.

Parameters
a_alphaThe scaling constant that multiplies the identity term.
a_betaThe scaling constant that multiplies the derivative term.

Implements TGAHelmOp< LevelData< FArrayBox > >.

Scales the right hand side of the Helmholtz equation by the identity term in the operator. This version assumes volume fraction weighting.

Parameters
a_rhsThe right hand side of the equation to be scaled.

Use your relaxation operator to remove the high frequency wave numbers from the correction so that it may be averaged to a coarser refinement. A point relaxtion scheme, for example takes the form a_correction -= lambda*(L(a_correction) - a_residual).

virtual void NWOViscousTensorOp::createCoarser ( LevelData< FArrayBox > &  a_coarse,

virtual

Create a coarsened (by two) version of the input data. This does not include averaging the data. So if a_fine is over a Box of (0, 0, 0) (63, 63, 63), a_fine should be over a Box (0, 0, 0) (31, 31, 31).
