virtual void	setLevelBC (int amrlev, const MultiFab levelbcdata, const MultiFab robinbc_a=nullptr, const MultiFab robinbc_b=nullptr, const MultiFab robinbc_f=nullptr) final override
	For cell-centered solves only: this must be called for each level. Argument `levelbcdata` is used to supply Dirichlet or Neumann bc at the physical domain; if those data are homogeneous we can pass nullptr instead of levelbcdata. Regardless, this function must be called. If used, the MultiFab levelbcdata must have one ghost cell. Only the data outside the physical domain will be used. It is assumed that the data in those ghost cells outside the domain live exactly on the face of the physical domain. Argument `amrlev` is relative level such that the lowest to the solver is always 0. The optional arguments robinbc_[a\|b\|f] provide Robin boundary condition `aphi + bdphi/dn = f`. Note that `d./dn` is `d./dx` at the upper boundary and `-d./dx` at the lower boundary, for Robin BC. However, for inhomogeneous Neumann BC, the value in leveldata is assumed to be `d./dx`. More...

bool	needsCoarseDataForBC () const noexcept
	Needs coarse data for bc? If the lowest level grids does not cover the entire domain, coarse level data are needed for supplying Dirichlet bc at coarse/fine boundary, even when the domain bc is not Dirichlet. More...

void	setCoarseFineBC (const MultiFab *crse, int crse_ratio) noexcept
	For cell-centered solves only: if we want to do a linear solve where the boundary conditions on the coarsest AMR level of the solve come from a coarser level (e.g. the base AMR level of the solve is > 0 and does not cover the entire domain), we must explicitly provide the coarser data. Boundary conditions from a coarser level are always Dirichlet. The MultiFab crse does not need to have ghost cells and is at a coarser resolution than the coarsest AMR level of the solve; it is used to supply (interpolated) boundary conditions for the solve. NOTE: If this is called, it must be called before `setLevelBC`. If crse is nullptr, then the bc values are assumed to be zero. More...
