In this proposal, a team comprising of HyPerComp and Aerojet-Rocketdyne shall create a computational system for the detailed modeling of the interaction of the human body with blast waves. The model will be able to address complex geometry and physics of the blast scene, as well as anatomical detail of the human body with adequate resolution. Nonlinear equations of state, adapted to individual tissues in the body shall be used in modeling the propagation of waves. Numerical techniques proposed here have been tested extensively in aerodynamics and propulsion applications in modeling multiphase and multi-material physics. The simulation suite shall comprise of human body models (with CAD/voxel import), graphical and interactive systems for simulation setup, automatic mesh generation, high performance computing and post-processing utilities. As this work progresses, additional capabilities to articulate the human body model and perform detailed (biologically relevant) flow-structure interaction shall be included in the system. Some innovations in performing broad parametric studies based on recent advances in reduced basis methods are proposed. It is believed that these methods can relieve some of the tedium involved in large scale computations involving multiple phenomena and physical inputs.

A new analysis and design tool for multiple antennas sited on a large platform is proposed, based on exact physics solutions of the 3-D Maxwells equations in the frequency domain. This tool uses the recently developed ultra-weak variational formulation (UWVF) to obtain equations for the tangential fields in a form that can be solved iteratively with almost perfect scalability on massively parallel computers, which will permit efficient solution for 1000 platforms. HyPerComp is well positioned to develop this tool due to equivalence of the UWVF to DG Galerkin formulation which we have applied to many large antenna/structure problems. HyPerComp is teaming with Professor Peter Monk from the University of Delaware, Professor Tim Warburton of Rice University, and Professor Tomi Huttunen of the University of Kuopio, Finland, in the development, implementation and validation of the UWVF code.

A pressure vessel includes a polymeric liner defining a fluid containment cavity and having an opening defining a port aperture extending between an inner surface and an outer surface of the polymeric liner and a rigid ring element is embedded within the polymeric liner and surrounding the port aperture. A metallic port element is disposed on the outer surface of the polymeric liner and fixed to the rigid ring element. A fiber composite material is disposed about the outer surface of the polymeric liner.

In this STTR project we aim to build software interfaces and enhancements to existing parallel mesh adaptation libraries for applications in high performance flow modeling. In Phase-I we demonstrated a preliminary implementation of such a system and identified technology needs. Phase-II development will include both open source, as well as commercially supported mesh adaptation software and interfaces. Tools will be provided for generating an initial mesh defined by CAD models as well as discretely specified pointwise/surface mesh based data. Highlights of this software will include mesh movement, handling curved geometry, very large scale parallelization, and appropriate mathematical machinery for high order data interpolation, mass and momentum conservation and error estimation in the adapted mesh. We will focus on the mesh generation and adaptation needs of the US Army PROTEUS simulation system in implicit free surface capture (using the level set method). The tools developed, however, will be more generally applicable. The team includes HyPerComp Inc., the Scientific Computation Research Center (SCOREC) at RPI and Simmetrix Inc., comprising of researchers with a long record of contributions in scientific computing and mesh generation.
