Algebraic Multilevel Preconditioning in Isogeometric Analysis: Construction and Numerical Studies
K. P. S. Gahalaut, S. K. Tomar, J. K. Kraus
We present algebraic multilevel iteration (AMLI) methods for isogeometric discretization of scalar second order elliptic problems. The construction of coarse grid operators and hie…
