Full constructor. Box is unghosted. When setting Lphi(i,j) = L(phi(i,j)) GhostVectPhi is the ghost vect of phi GhostVectLph is the ghost vect of lphi

Second constructor for creating stencil where dest and src live on 2 different levels and dest is Lphi and src is Phi. no relax optimization here

Member Function Documentation
| void EBStencil::apply | ( | EBCellFAB & | a_lofphi, | |
| const EBCellFAB & | a_phi, | |||
| bool | incrementOnly = false | |||
| ) | const |
Applies stencil to each component of phi using the stencil weights and offsets to compute L. If incrementOnly = true, a_lofphi is incremented without any set to zero. If false, a_lofphi is set to zero and set equal to L(phi).
| void EBStencil::apply | ( | EBCellFAB & | a_lofphi, | |
| const EBCellFAB & | a_phi, | |||
| const BaseIVFAB< Real > & | a_alphaWeight, | |||
| Real | a_alpha, | |||
| Real | a_beta, | |||
| bool | incrementOnly = false | |||
| ) | const |
Applies stencil to each component of phi using the stencil weights and offsets to compute L. but with constants. a_lofphi_i = alpha*phi_i + beta*lphi_i If incrementOnly = true, a_lofphi is incremented without any set to zero. If false, a_lofphi is set to zero and set equal to a_lofphi_i Alpha and beta are defined over getIrregIVS(lphBox) where lphBox = grow(a_box, a_ghostVectLph) where a_box are given in the constructor.
