Little Beast Engineering

This entity specializes in three-dimensional modeling tools and expert services for transient simulations of magnets.

Its core commercial product is the Rat Graphical User Interface (GUI), a design tool for magnet systems, which is available for purchase following a thirty-day free trial. The Rat GUI provides convenient access to the open-source Rat Library's 3D magnetostatic field calculation capabilities, allowing users to visualize 3D coil geometries and field calculation outputs in real-time. It includes features for designing complex coil shapes, such as Canted Cosine Theta (CCT) coils with longitudinally varying harmonics.

The company also offers specialized simulation services using its proprietary Raccoon tool. This tool, equipped with a fully three-dimensional electromagnetic and thermal network solver, is employed for complex analyses like quench behavior and ramp-up/down scenarios, particularly for non or partially insulated coils. The Raccoon software itself is not for sale; its capabilities are delivered as a service.

Furthermore, the firm extends expert guidance on superconducting magnets, encompassing both high-temperature (HTS) and low-temperature (LTS) varieties.

Revenue streams are derived from sales of the Rat GUI, fees for custom simulation projects conducted with the Raccoon tool, and charges for expert consultancy. The business targets entities engaged in magnet design and analysis, likely within research, specialized engineering, or manufacturing sectors that depend on precise magnetic field modeling. The development of the Rat GUI by Little Beast Engineering is also structured to support the continued advancement of the open-source Rat Library, noted for its C-based implementation and rapid magnetic field calculations via the Multi-Level Fast Multipole Method.
