HOBBIES is a versatile electromagnetic simulation software designed to accurately solve a wide range of electromagnetic engineering problems, including scattering, radiation, and electromagnetic compatibility. One of its most notable features is its ability to handle ultra-large-scale electromagnetic models with high precision, making it a powerful tool for complex engineering applications.
The technical strengths of HOBBIES are rooted in several key innovations:
1) **Ultra-large-scale parallel computing**: HOBBIES demonstrates exceptional performance when handling large-scale simulations, achieving over 90% parallel computing efficiency on thousands of cores. This makes it highly suitable for solving computationally intensive problems.
2) **Efficient out-of-core solution technology**: For massive electromagnetic targets like ships or aircraft formations, where memory limitations can hinder traditional methods, HOBBIES uses advanced out-of-core techniques that maintain performance at over 90% of physical memory capacity. In comparison, other software typically achieves less than 60% efficiency in such scenarios.
3) **Advanced computational methods**: The software incorporates state-of-the-art algorithms, such as the high-order moment method, multi-layer fast multipole method, high-low frequency mixing method, and automatic reduced moment method. These allow for both speed and accuracy in complex calculations.
4) **High-efficiency Multi-Objective Optimizer (HEMO)**: HEMO is a powerful optimization module within HOBBIES, enabling multi-objective design tasks such as antenna layout, array configuration, radar cross-section (RCS) reduction, and system-level electromagnetic compatibility analysis.
The shape of the carrier significantly influences the performance of detailed models of large-scale phased array antennas.
Analysis of electromagnetic interference among ship formations.
Electromagnetic field analysis of microwave weapons.
**Typical application of HOBBIES software**
With nearly three decades of technological development, HOBBIES has become a leading solution in the field of computational electromagnetics. Institutions such as NAVAIR, NRL, LOCKHEED MARTIN, and SRC continue to rely on HOBBIES for critical projects involving electromagnetic characteristics design. Its advanced technologies enable users to achieve hundreds of times higher hardware investment efficiency, dramatically increase calculation speed, and tackle numerous high-precision, large-scale electromagnetic problems.
HOBBIES has been introduced to China and has already completed over 1,000 CPU parallel computations at the Shanghai Supercomputing Center. Its parallel computing efficiency has exceeded expectations, even by HPC researchers.
**Typical applications include:**
1) **Design and layout of airborne phased array antennas**: HOBBIES can efficiently simulate high-frequency antennas with large model sizes, matching the scale of the aircraft body.
2) **Aircraft carrier radar characteristics analysis**: As a robust large-scale electromagnetic simulation tool, HOBBIES can easily handle the complexity of an aircraft carrier carrying 61 fighters and 6 helicopters.
3) **Aircraft formation radar characteristics analysis**: HOBBIES is capable of simulating the radar electromagnetic scattering of multiple fighter formations.
4) **Spaceborne antenna layout calculation**: HOBBIES allows for individual modeling of spaceborne antennas, building satellite ontology models, and using full-wave computation capabilities to accurately evaluate changes in electrical properties after installation.
**Vehicle formation environment stealth design**
**MiG-29 radar detectable distance estimate**
