We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

  I am planning to perform a coupled magnetic field analysis and structural analysis of a flexible magnet. However, I am not sure if the magnetization direction also changes with the deformation of the structure, so I asked this question. I would appreciate it if you could tell me.

  Hello, the magnetization direction is input quantity in Maxwell, it won't change with the deformation of the structure.

  Thank you for reply.
  Then, how can I perform a coupled magnetic field analysis and structural analysis of a deforming magnet?

    We can use solid226 coupled field elements (AZ,UX,UY,UZ dof) with nlgeom on, and the magnetization vector direction will be updated.
    (There is no example in the help manual so it is very hard to set this up if you do not have any experience with MAPDL)
    
    Since like in Maxwell we mesh (MAPDL) the air domain around the magnet, we can only have small deformations of the magnet, otherwise air elements will distort too much and solution will fail/stop (due to high element distortion).
    
    If you have very large deformations (structure) then we can not do this.
    All the best
