seeking help with magnetoelastic couping simulation

[Qxiao]

I am using the magnetoelastic module to calculate the influence of magnetoelastic coupling on the magnetic structure. However, I have encountered some problems during this process and would appreciate your assistance.

 When I imported the steady-state file obtained from muMax calculations as the initial state for magnetoelastic simulations, the structure was still disrupted after the relaxation process, even though only the corresponding parameters were set and no strain or displacement was applied. In contrast, the structure remained stable during relaxation when I disabled the periodic boundary conditions (PBC), or when I set both B₁ and B₂ to zero while keeping the PBC enabled.

   Additionally, I would like to understand the differences between setting parameters such as exx, setting u, and configuring frozendisploc and frozendispval when applying strain or displacement, as well as how I should properly use these settings. I look forward to your assistance.
