We study an algebraic multigrid (AMG) method for solving elliptic finite element equations of linear elasticity problems. In this method, which has been proposed in (Kraus, SIAM J Sci Comput 2008; 30: 505–524), the coarsening is based on the so‐called edge‐matrices, which allows to generalize the concept of strong and weak connections, as used in the classical AMG, to ‘algebraic vertices’ that accumulate...
