High-fidelity electromagnetic analysis and radio frequency simulation is only as sound as the geometric computer models upon which the analysis is based. Within the Aerospace/Defense Industry, Navionics is known by its reputation for producing high-quality 3-Dimensional aircraft, missile, and antenna finite-element meshed computer models. These models are suitable for generalized 3D MOM (Method Of Moments) analysis and can be produced within short turnaround times. Additionally, treatment zones can be provided to the customer in the form of bulk dielectric regions or impedance boundary-condition surfaces. Navionics is also pleased to offer analysis, optimization, and consulting services. |

"In August 1995, McDonnell-Douglas Aerospace used CARLOS-3D and Intel's ProSolver-DES dense equation solver routines to run what analysts say is the largest matrix ever solved with those methods. The problem, a model of the F/A-18C fighter created by Navionics Research (Saint Louis, MO), exploited matrix symmetry to create two matrices, each of rank 114,240, giving a total of 228,480 unknowns. The model included 149,636 facets, and the simulation was performed at 500MHz. The machine that solved the problem is a Paragon supercomputer with 392 parallel Pentium processors and 32MB of memory per processor. Large, dense matrices typically require swapping out the matrix to disk. McDonnell-Douglas' Paragon system is configured with 10 SCSI-16 RAID units that yield a disk space of 168GB. The machine took 16 hours to fill the matrices, 65 hours for factorization, and 3.5 hours to solve for the electromagnetic currents at 362 radar illumination aspects."...
