Weapon System Performance in Complex Radio Frequency (RF) Environments

In this proposed effort we seek to develop mesh repair algorithms that optimize preexisting meshes for CEM full wave solvers. We will investigate automated methods for converting asymptotic meshes to full wave CEM solver meshes. Mesh repair modules will implemented and accessed from a stand-alone tool with 3-D visualization capabilities or via C++ libraries that may be added to existing codes. The modules will include mesh resolution and quality repair capabilties using smoothing and mesh regeneration techniques. Mesh connectivity repair will be provided by a method that performs automatic restitching of the mesh across unconnected mesh boundaries. Procedures for converting asymptotic meshes to four sided surfaces, such that new fully connected mesh may be generated, will be implemented and tested. HyPerComp's many years of experience with grid generation technologies makes it well positioned to successfully implement the proposed techologies and provide greater usefullness for preexisting meshes, which can be very time consuming to create.
