## Coupled Fluid-Flexible Body Investigation Using Chrono::Fluid

The interaction of fluid-flexible bodies was studied via a Lagrangian-Lagrangian framework, relying on Smoothed Particle Hydrodynamics, a general 3D rigid body dynamics, and an Absolute Nodal Coordinate Formulation (ANCF). The dynamics of the two phases, …

## Characterization of Xeon Phi with Linear Algebra Workloads

The efforts behind this independent study are to analyze how well suited Xeon Phi is for some frequently used linear algebra routines such as factorization and solvers. We are working with Intel MKL 11.1 on …

## Performance Analysis of CULA on different NVIDIA GPU Architectures

The CULA is a next generation linear algebra package that uses the GPU as a co-processor to achieve speedups over existing linear algebra packages. CULA supports matrix inversion operation which helps in solving and factorizing …

## Performance Comparison Study between NVIDIA Fermi and Kepler Architecture

A comparative study between Nvidia Fermi and Kepler architectures are being undertaken. The key aspects being targeted are performance scaling for computational kernels like tiled matrix multiplication, memory transfer behavior, gains using streaming and performance …

## Selective Laser Sintering Simulation Using Chrono::Engine

This project presents an effort to use physics based simulation techniques to model the Selective Laser Sintering (SLS) layering process. SLS is an additive manufacturing process that melts thin layers of extremely fine powder; we …

A Primal-Dual Interior Point (PD-IP) method is investigated for solving the Cone Complementarity Problem (CCP) associated with friction and contact of many body dynamics formulated by the framework of differential variational inequality (DVI). As a …

## Cross-Sectional Pattern in Mixing of Granular Material

This simulation is modeled after Spontaneous chaotic granular mixing by Shinbrot, Alexander, and Muzzio. A mixing barrel is filled with sand-sized particles with different colored particles upstream and downstream. The fractal pattern that emerges in …

## Robot Walking on Granular Terrain

The simulation consists of a six-legged robot which walks over granular terrain. This project begins to model the experiment presented in A Terradynamics of Legged Locomotion on Granular Media by Li, Zhang, and Goldman. Currently, …

## A Multibody Dynamics-Enabled Mobility Analysis Tool for Military Applications

This project demonstrates a modeling, simulation, and visualization framework aimed at enabling physics-based analysis of ground vehicle mobility. This framework, called Chrono, has been built to leverage parallel computing both on distributed and shared memory …
