“…The dimensionality of the parameter domain which describes any sufficiently rich set of possible systems -note that the parametrization characterizes material properties, geometry, boundary conditions, and also topology -precludes application of the classical pMOR approaches due to the well-known curse of dimensionality. Within the context of time-domain elastodynamics of large geometric domains with localized excitations, the recently developed two-level PR-RBC method [40] is of great interest. The latter takes advantage of domain decomposition techniques [41,42,43,44,45] and the frequency-time duality [46,47] to construct the reduced bases.…”
