Guilkey THE UNIVERSITY OF UTAH GRADUATE SCHOOL FINAL READING APPROVAL To the Graduate Council of the University of Utah: I have read the dissertation of Michael Dietel Steffen in its final form and have found that (1) its format, citations, and bibliographic style are consistent and acceptable; (2) its illustrative materials including figures, tables, and charts are in place; and (3) the final manuscript is satisfactory to the Supervisory Committee and is ready for submission to The Graduate School. Date Robert M. Kirby Chair, Supervisory Committee Approved for the Major Department Martin Berzins Chair/Dean Approved for the Graduate Council Charles A. Wight Dean of The Graduate School ABSTRACT The Material Point Method (MPM) has shown itself to be a powerful tool in the simulation of large deformation problems, especially those involving complex geometries and contact where typical finite element type methods frequently fail. While these large complex problems lead to some impressive simulations and so- lutions, there has been a lack of basic analysis characterizing the errors present in the method, even on the simplest of problems. -
Scalable Large-Scale Fluid-Structure Interaction Solvers in the Uintah Framework Via Hybrid Task-Based Parallelism Algorithms
1 Scalable Large-scale Fluid-structure Interaction Solvers in the Uintah Framework via Hybrid Task-based Parallelism Algorithms Qingyu Meng, Martin Berzins UUSCI-2012-004 Scientific Computing and Imaging Institute University of Utah Salt Lake City, UT 84112 USA May 7, 2012 Abstract: Uintah is a software framework that provides an environment for solving fluid-structure interaction problems on structured adaptive grids on large-scale science and engineering problems involving the solution of partial differential equations. Uintah uses a combination of fluid-flow solvers and particle-based methods for solids, together with adaptive meshing and a novel asynchronous task-based approach with fully automated load balancing. When applying Uintah to fluid-structure interaction problems with mesh refinement, the combination of adaptive meshing and the move- ment of structures through space present a formidable challenge in terms of achieving scalability on large-scale parallel computers. With core counts per socket continuing to grow along with the prospect of less memory per core, adopting a model that uses MPI to communicate between nodes and a shared memory model on-node is one approach to achieve scalability at full machine capacity on current and emerging large-scale systems. For this approach to be successful, it is necessary to design data-structures that large numbers of cores can simultaneously access without contention. These data structures and algorithms must also be designed to avoid the overhead involved with locks and other synchronization primitives when running on large number of cores per node, as contention for acquiring locks quickly becomes untenable. This scalability challenge is addressed here for Uintah, by the development of new hybrid runtime and scheduling algorithms combined with novel lockfree data structures, making it possible for Uintah to achieve excellent scalability for a challenging fluid-structure problem with mesh refinement on as many as 260K cores. -
The Material-Point Method for Granular Materials
Comput. Methods Appl. Mech. Engrg. 187 (2000) 529±541 www.elsevier.com/locate/cma The material-point method for granular materials S.G. Bardenhagen a, J.U. Brackbill b,*, D. Sulsky c a ESA-EA, MS P946 Los Alamos National Laboratory, Los Alamos, NM 87545, USA b T-3, MS B216 Los Alamos National Laboratory, Los Alamos, NM 87545, USA c Department of Mathematics and Statistics, University of New Mexico, Albuquerqe, NM 87131, USA Abstract A model for granular materials is presented that describes both the internal deformation of each granule and the interactions between grains. The model, which is based on the FLIP-material point, particle-in-cell method, solves continuum constitutive models for each grain. Interactions between grains are calculated with a contact algorithm that forbids interpenetration, but allows separation and sliding and rolling with friction. The particle-in-cell method eliminates the need for a separate contact detection step. The use of a common rest frame in the contact model yields a linear scaling of the computational cost with the number of grains. The properties of the model are illustrated by numerical solutions of sliding and rolling contacts, and for granular materials by a shear calculation. The results of numerical calculations demonstrate that contacts are modeled accurately for smooth granules whose shape is resolved by the computation mesh. Ó 2000 Elsevier Science S.A.

Raymond · Bruce Jones · John R. Williams Received: date / Accepted: date Abstract A strategy is introduced to allow coupling of the Material Point Method (MPM) and Smoothed Particle Hydrodynamics (SPH) for numerical simulations. This new strategy partitions the domain into SPH and MPM regions, particles carry all state variables and as such no special treatment is required for the transition between regions. The aim of this work is to derive and validate the coupling methodology between MPM and SPH. Such coupling allows for general boundary conditions to be used in an SPH simulation without further augmentation. Additionally, as SPH is a purely particle method and MPM is a combination of particles and a mesh, this coupling also permits a smooth transition from particle methods to mesh methods. -
