To avoid the common volumetric locking i ssues at high Poisson's ratios of linear finite element methods (FEM), we build MiNNIE upon a mixed FEM framework and further incorporate a pressure stabilization term to ensure excellent convergence of multigrid solvers. Our pressure stabilization strategy injects bounded influence on nodal dis placement which can be eliminated using a quasi-Newton method. MiNNIE has a specially tailored GPU multigrid solver including a modified skinning-sp ace interpolation scheme, a novel vertex Vanka smoother, and an efficient dense solver using Schur complement. MiNNIE supports various elastic mater ial models and simulates them in real-time, supporting a full range of Poi sson's ratios up to 0.5 while handling large deformations, element inversi ons, and self-collisions at the same time.\n\nRegistration Category: Full Access, Full Access Supporter\n\nLanguage Format: English Language\n\nSess ion Chair: Sheldon Andrews (École de technologie supérieure (ÉTS)) URL:https://asia.siggraph.org/2024/program/?id=papers_148&sess=sess141 END:VEVENT END:VCALENDAR
