High Field Hybrid Magnet 

Best Solution's customer, Oxford Instruments are world leaders in the design and manufacture of special superconducting magnets. Best Solution were able to provide modelling support on a high field, hybrid magnet project, which used a combination of superconducting, and copper coils, for a magnet with a bore flux density of up to 40 Tesla. 
The challenges in the magnet design were extreme, and transient modelling of coupled magnetic-stress and magnetic-thermal-stress fields were required in order to enable parts of the structure to be designed to withstand the enormous forces of a quench.

Support structure for superconducting 'outsert' coils 
Contours of displacement and Von-Mises stress due to thermal loads (reduced finite element model due to periodic symmetry)
