ApInvC

std::vector<MatrixX> pbat::sim::vbd::multigrid::HyperReduction::ApInvC

|#levels| list of 4x|4*#clusters| of A_p^{-1} matrices, such that A_p's coefficients are \int_{\Omega^c} P_i(X) P_j(X) dx, where \Omega^c is cluster c's domain, and P_k(X) is the k^{th} polynomial basis.

C

std::vector<IndexVectorX> pbat::sim::vbd::multigrid::HyperReduction::C

Hierarchical clustering of mesh elements.

|#levels| list of clustering maps from fine level to coarse level, i.e. maps u^{l} to u^{l+1}
