◆ matchBC()

		const bool	a_homogeneousPhysBC,
		const DataIndex &	a_dit

Match the BC.

MFhelmholtzJumpBC uses a_jump as the fixed parameter, computing the fluxes from the boundary potential and surface source. This function, however, specifies a zero flux into one of the phases and uses a_jump as a free parameter (it is computed from the fluxes).

Parameters

[out]	a_jump	Jump data, i.e. right-hand side of dphi/dn + dphi/m = jump. Set equal to jump = b*dphi/dm.
[in]	a_phi	Cell-centered data
[in]	a_homogeneousPhysBC	Homogeneous BC or not
[in]	a_dit	Grid index
