Recently significant advances have been made in the high fidelity modeling of electromagnetic phenomena in complex geometries in the time-domain. To make high fidelity simulations of scattering and radiation tractable, the computational region must be truncated in a manner allowing outgoing waves to leave with minimal reflection from the boundary. We, HyPerComp in collaboration with Profess ...

The principal elements for creating an efficient, accurate, and robust suite of tools for combined radome/antenna design are currently within view. The challenge is to integrate these elements in a package that is easily applied to optimizing radar system performance when the antenna is installed on a specific platform behind a radome that must meet both structural and aerodynamic constraints. S ...

HyPerComp, Inc. in collaboration with Professor Patrick Lynett of Texas A & M University is developing a comprehensive approach to providing realistic geometric models for small craft moving in a littoral environment, including representations for the sea surface, suitable for use in computing radar returns from the combined surfaces using currently available electromagnetic solvers. In this effor ...

HyPerComp proposes to build on its strengths in developing high order discontinuous Galerkin (DG)-based methods, uncertainty quantification and reduced order-basis methods and investigate some novel ideas for modeling large-scale antenna/structure coupling problems of interest to the Navy. Some of the technologies to be considered are, 1) Physics-based accurate modeling of EM scattering from compl ...

In this proposed effort we seek to develop and integrate CAD repair algorithms with our existing highly capable geometry manipulation and grid generation software with the goal of greatly decreasing the time spent generating grids for complex geometry configurations as part of the numerical simulation problem setup. Highly detailed CAD models are critical for design and manufacture of a wide varie ...

In this proposal, a team comprising of HyPerComp Inc. and NASA-JPL aims to develop modular parallel adaptive meshing capability for problems involving implicitly captured interfaces such as free surface capture using the level set method. In specific, these models will be demonstrated along with the appropriate software interfaces for the US Army PROTEUS toolkit. The foundation for this developmen ...

Building on HyPerComp"s strengths in developing high order physics-based solvers in multidisciplinary technologies in electromagnetics and fluid dynamics, we have now embarked on a new high order framework (being named High Definition-Physics (HDPhysics)) for solving time-domain Maxwell"s equations based on the nodal discontinuous Galerkin (DG) formulation. This new framework has many new feature ...

ABSTRACT: In this proposal we suggest a two pronged approach to obtaining fast and efficient solutions to whole-body thermal response of tissue to RF exposures. The first, is the application of high fidelity electromagnetics and heat transfer solvers using high performance computing tools and techniques to obtain fast individual solutions. A multiphysical CPU/GPU based unstructured mesh solver su ...

A comprehensive approach is proposed to develop and integrate tools for computationally obtaining radar signatures of small watercraft in dynamic seas over many simulation steps.
