In Maxwell 3D, how can one simulate a set of connected large metallic vacuum chambers (10-20 meters long, 2 meters in diameter) with small thickness (15 mm)? These vacuum chambers are located in an area where a low frequency oscillating field from a coil is applied (f ~ 3 Hz – 5000 Hz).
The goal of the simulation is to find the eddy currents distribution in the chamber walls along with the transmitted magnetic field inside the tower as a function of the applied field frequency as well as a function of the permeability and conductivity of the chamber material.
The difficulty is to mesh such a system. In Comsol there is a way to avoid 3D meshing of the chamber walls thickness by replacing them by an average surface to which a special “transition boundary condition” is applied. Is this feasible in Maxwell 3D?<\/p>\n

Thanks a lot for any help\/hints.<\/p>\n","protected":false},"template":"","class_list":["post-374204","topic","type-topic","status-closed","hentry","topic-tag-quasi-static-1","topic-tag-maxwell"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
