Description
Fusion magnets for so-called compact high-field machines present a new challenge for designers. Tools for fast assessment of magnet pre-designs are needed, and a new mechanical toolbox called CIRCE has been developed.
New updates to the analysis tool will be presented, including improved winding pack and casing contact, a detailed inner leg interface between adjacent tf coils and additional support strategies. The new code structure makes joint use of Matlab and Cast3M finite element software, facilitating parametric studies that highlight trends associated with certain mechanical parameters. Advanced post-treatment has been added with first estimates of component stresses and thorough analysis of load distribution in the vault and inter-coil structures.
Emphasis will be placed on the study of out-of-plane effects. The torsional stiffness of the toroidal system is characterized in several configurations, including the bucked and wedged option. Finally, an application of CIRCE to a Stellarator design demonstrates the tool’s great flexibility, paving the way for future studies.
