HPC based high-resolution modelling of magnets

Magneti produces its magnets through a process called compaction, which uses a hydraulic press to apply pressure to magnetic powders until they solidify. The hydraulic press is made up of several very expensive parts which regularly wear out and must be replaced. The pressing tool needed to be optimized, so it could be used for longer and with lower material costs, but doing this requires the ability to automatically detect yielding of the tool under a given pressure. This requires many iterations of computer simulation and post-processing, which exceeds in-house capabilities.


The Solution
To tackle the problem of pressing tool optimization, XLAB developed a set of software services based on open-source solutions. XLAB built a computer model of the pressing tool and its behaviour during the compaction process. This model is highly configurable, so Magneti can reuse it for other applications.
The optimization service runs as a web application, which provides an easy-to-use interface. The application connects to Arctur’s HPC system and submits an HPC job according to configuration and input parameters from the end user. This means that even inexperienced users are able to design and run experiments using HPC resources, avoiding the need for costly training. Magneti only needs to pay for the computing resources it uses, providing the company with a cost-effective solution.

Business Impact
For Magneti, there are several benefits. Due to the optimized geometric properties of the pressing tool, the quantity of excess material in an existing tool was reduced by around 32%, reducing material costs. This has reduced the cost of making the pressing tool by 27%, which represents an annual saving of €87k. The pressing tool is also of a higher quality, containing narrower coils which consume less power. Assuming Magneti replaces all of their pressing tools with those designed by the HPC tool, this will save another €16.2k annually.

Design of a better pressing tool that saves money, does not need to be replaced as often, and uses less energy.
Savings of over €100,000 per year for Magneti and ability to create new services based on improved pressing tool.
