◆ adjustRHSAtCoarseFineBoundary() [1/2]

void IBTK::PoissonUtilities::adjustRHSAtCoarseFineBoundary ( SAMRAI::pdat::CellData< NDIM, double > &  rhs_data,
const SAMRAI::pdat::CellData< NDIM, double > &  sol_data,
SAMRAI::tbox::Pointer< SAMRAI::hier::Patch< NDIM > >  patch,

)
static

Modify the right-hand side entries to account for coarse-fine interface boundary conditions corresponding to a cell-centered discretization of the Laplacian.

Note
This function simply uses ghost cell values in sol_data to provide Dirichlet boundary values at coarse-fine interfaces. A more complete implementation would employ the interpolation stencil used at coarse-fine interfaces to modify both the matrix coefficients and RHS values at coarse-fine interfaces.

◆ adjustRHSAtCoarseFineBoundary() [2/2]

void IBTK::PoissonUtilities::adjustRHSAtCoarseFineBoundary ( SAMRAI::pdat::SideData< NDIM, double > &  rhs_data,

)
static

Modify the right-hand side entries to account for coarse-fine interface boundary conditions corresponding to a side-centered discretization of the Laplacian.

Note
This function simply uses ghost cell values in sol_data to provide Dirichlet boundary values at coarse-fine interfaces. A more complete implementation would employ the interpolation stencil used at coarse-fine interfaces to modify both the matrix coefficients and RHS values at coarse-fine interfaces.

Modify the right-hand side entries to account for coarse-fine interface boundary conditions corresponding to a side-centered discretization of the variable coefficient viscous operator.
