A new multigrid or incomplete LU technique is developed in this paper for solving large sparse algebraic systems from discretizing partial diierential equations. By exploring some deep connection between the hierarchical basis method and incomplete LU decomposition, the resulting algorithm can be eeectively applied to problems discretized on completelyunstructured grids. Numerical experiments demonstrating the eeciency of the method are also reported.
