This is the error I got over time: Rotating Machinery, Magnetic, Nonconducting Magnet 14: Defining only a fraction of north and south possible only if a pattern is specified and identifiable. Domains: 4, 5, 10, 14, 15, 17, 19, 21, 22, 24, 2.
However, I have done the following;
1. created a selection for north and south poles for individual magnets
2. created a physics under the domain for nonconducting magnets but only 1 out of 12 is active
Dear friend Isiaka Shuaibu
It seems that you are trying to model an axial flux machine using COMSOL Multiphysics and encountering an error when defining the magnets. The error message suggests that only a fraction of the north and south poles have been defined, and this is not possible unless a pattern is specified and identifiable.
To define the magnets in COMSOL Multiphysics for an axial flux machine, you can follow these general steps:
In order to avoid the error message, you encountered, make sure that you have defined all the north and south pole selections for each magnet. If you have only defined a subset of the poles, you will need to specify a pattern that identifies the missing poles. This can be done using the "Pattern" option in the Nonconducting Magnet feature.
Also, make sure that all of the domains that contain magnets have been properly assigned with the Nonconducting Magnet features. It is possible that you have missed one of the domains, which could be causing the issue.
Finally, check that the magnet properties and boundary conditions are correctly defined, as any errors in these settings can also cause issues with the simulation.
If you continue to encounter errors, you may want to consult the COMSOL Multiphysics documentation or seek assistance from the COMSOL support team. That is always the choice.
