The US Air Force Research Laboratory, Directed Energy Directorate, has developed and patented two world class software modules to solve simulation problems: CUBEGEN™ and TMax™ software.
CUBEGEN™ software is a highly accurate and fast Cartesian mesh generation technique with colossal cell capacity using minimal computation and storage resources. This feat is accomplished by using a memory efficient ray tracing method, a highly accurate ray-facet intersection test, and a novel exact tie-breaking algorithm for rays intersecting facet edges and vertices. Because of exact arithmetic operations, the automated generated mesh is almost always right the first time – no user intervention or iteration needed.
If electromagnetic simulation were desired, TMax™ software then solves Maxwell equations on the CUBEGEN™ Cartesian mesh using the finite difference time domain method and generates output. Other solvers can be applied on the CUBEGE™ mesh to solve problems of interest to other disciplines such as CFD.
- Fast and efficient: CUBEGEN™ software can almost always get the mesh right the first time – no iteration needed; it can easily generate a 10 billion cell volume on a laptop and a trillion cell volume on a workstation. TMax™ software can easily simulate a 2 billion cell volume on a workstation.
- Accurate with high resolution: With this high resolution capability, complex shapes can be modeled accurately; errors such as stair stepping and numerical dispersion are negligible.
- Benefits realizable by users with million cell problems: Modelers solving million cell and larger problems will see noticeable efficiency and resolution gains.
- Compatible with nearly all CAD packages: Reads standard tessellation language (STL) format.
- TMax™ software used for mission essential projects including: RF illumination of printed circuit board; lightning strike field penetration; helix antenna; engine stopper; and cargo-bay RF penetration
- Code in Fortran 90; TMax™ software user manual complete
- Patent 8,059,122 – Cartesian Mesh Generation Technique – and software modules available for license
- Potential for collaboration with US Air Force Research Laboratory inventor
