AB - <p style="text-align: justify;">We introduce a new multigrid method to study the lattice statics model arising from nanoindentation. A constrained Cauchy-Born elasticity model is used as the
coarse-grid operator. This method accelerates the relaxation process and considerably
reduces the computational cost. In particular, it saves quite a bit when dislocations
nucleate and move, as demonstrated by the simulation results.</p>
