The core components of our simulator are an adaptive subspace oracle, mode l, and parallel time-step solver algorithm. Our in-time-step adaptivity or acle continually assesses subspace solution quality and candidate update p roposals while accounting for temporal variations in deformation and spati al variations in material. In turn our adaptivity model is subspace agnost ic. It allows application across subspace representations and expresses un restricted deformations independent of subspace choice. We couple our orac le and model with a custom-constructed parallel time-step solver for our e nriched systems that exposes a pair of user tolerances which provide contr ollable simulation quality. As tolerances are tightened our model converge s to full-space solutions (with expected cost increases). On the other han d, as tolerances are relaxed we obtain output-bound simulation costs. We d emonstrate the efficacy of our approach across a wide range of challenging nonlinear materials models, material stiffnesses, heterogeneities, dynami c behaviors, and frictionally contacting conditions, obtaining scalable an d efficient simulations of complex elastodynamic scenarios.\n\nRegistratio n Category: Full Access, Full Access Supporter\n\nLanguage Format: English Language\n\nSession Chair: Paul Kry (McGill University) URL:https://asia.siggraph.org/2024/program/?id=papers_609&sess=sess126 END:VEVENT END:VCALENDAR
