Classes
class	terra::linalg::solvers::TwoGridGCA< ScalarT, Operator >
	: Galerkin coarse approximation (GCA). TwoGridGCA takes a coarser and a finer operator. Each thread assembles a coarse-grid gca matrix in the coarser operator on a single hex. To do this, it loops the finer hexes of the coarse hex and its respective wedges. It computes the interpolation matrix P mapping from coarse wedge to the current fine wedge, computes the triple-product P^TAP with the fine-operator local matrix A and adds the resulting gca matrix up for all fine wedges comprising the coarse wedge. Finally, it stores the result in the wedge-wise matrix storage of the coarse operator. More...
