Detailed Description

Class which computes a bi/tri-linear stencil in cut-cells. This class makes appropriate modifications if one of the cells don't exist, and even if there are multivalued cells present.

Note

This routine assumes that the data is fundamentally cell-centered.

This only does interpolation along the input coordinate. The other coordinates are ignored.

Parameters

[out]	a_stencil	Interpolation stencil
[in]	a_pos	Relative position inside cell
[in]	a_vof	Cut-cell
[in]	a_domain	Domain
[in]	a_interpDir	Interpolation coordinate

Returns

Computed interp stencil1 d

Parameters

[in]

a_ebisbox

Ebisbox

computeInterpStencil2D()

bool LinearStencil::computeInterpStencil2D ( VoFStencil &  a_stencil, const RealVect &  a_pos, const VolIndex &  a_vof, const ProblemDomain &  a_domain, const EBISBox &  a_ebisbox, const int  a_noInterpDir = 2  )

Compute a bilinear interpolation stencil.

This ignores interpolation along the input coordinate.

Parameters
