dc.description.abstract [EN] In this work, we adapt a Total Reuse of Krylov Subspaces for usage in a GMRESsolver and apply it to nonlinear structural-dynamics examples. These examples are then solved by a multirate FETI-method, the nonlinear BGC-macro method, which allows local subcycling in time within substructures, such that local time-stepping is performed between synchronizationtime-steps. In these proposed examples, we show that the reuse-method reduces the total number of GMRES-iterations and shifts the eigenvalue-spectrum of the global system towards smaller eigenvalues. es_ES
