The Heistracher et al. standard problem tests domain wall pinning at the interface of a two-phase magnetic rod. It is sensitive to discontinuities in the exchange constant $A$, uniaxial anisotropy $K$, and spontaneous polarisation $J_s$ between phases, making it a targeted test for correct interface handling.
