Abstract
We propose an efficient geometric multigrid (GMG) strategy for finite element (FE) meshes of non-uniform refinement levels. The suggested method exploits that levels of high resolution usually extend over small sub-domains only. By restricting all fine level smoothing operations to the corresponding partial meshes, memory consumption and operation count are kept at a minimum
