Multigrid Method for Solving Three-Dimensional Implicit Solid Mechanics Problems

This paper describes a parallel multigrid method for solid mechanics problems on unstructured finite element meshes using a distributed memory model with MPI and Fortran90. The implementation shows good speedup and scalability on several high-performance computers, although the floating-point performance is below the machines' peak capabilities.

Ship Concept Exploration and Development Ship Concept Exploration and Development

Virginia Tech AOE

This presentation describes a systems engineering method for early-stage naval ship design. It uses multi-objective optimization to balance cost, risk, and effectiveness. The process integrates Computational Fluid Dynamics (CFD) to provide key predictions for a ship's hydrodynamic resistance and seakeeping, enabling a more data-driven approach to evaluating new designs.

BRIDGING THE GAP IN UNDERSTANDING BONE AT MULTIPLE LENGTH SCALES USING FLUID DYNAMICS

Eric James Anderson

This technical paper investigates the role of fluid flow in bone remodeling by employing computational fluid dynamics to bridge the knowledge gap between tissue-level and cellular-level understanding. It uses CFD models to predict mechanical forces and fluid parameters at the nano-micro scale, which are currently immeasurable through direct observation. The work also applies these findings to optimize in vitro cell flow devices and tissue engineering scaffolds.

Filtration Theory Using Computer Simulations

Werner Bergman and Ivan Corey

This technical paper applies Computational Fluid Dynamics principles to simulate filtration, using Navier-Stokes theory and the Langevin particle equation to model particle capture and pressure drop through fiber arrays. The work integrates various particle capture mechanisms into a single simulation framework, offering a comprehensive approach to understanding filtration performance.

Liquid Filtration Simulation

Ivan Corey and Werner Bergman

This technical paper delves into the simulation of liquid filtration, demonstrating a practical application of Computational Fluid Dynamics to analyze and predict the behavior of fluids and particles within filter structures. The work is crucial for advancing the understanding of filtration processes and developing more effective separation technologies.
