Abstract:
In this article, a fully aggregation‐based algebraic multigrid strategy is developed for nonlinear contact problems of saddle point type using a mortar finite element approach. While the idea of extending multigrid methods to saddle point systems can already be found, for example, in the context of Stokes and Oseen equations in literature, the main contributions of this work are (i) the development and open‐source implementation of an interface aggregation strategy specifically suited for genera...     »
