Simulating non-linear magnetic tearing instability across an anisotropic Harris current sheet. Cyclic external compression drives Sweet-Parker current sheet thinning, triggering X-point collapse, secondary plasmoid chain coalescence, and bidirectional relativistic exhaust jets into the ambient basin.
Where the shear front from the upper terraces intersects the colder Widmanstätten flats, the ground polarizes into opposing field sheets. 当薄层厚度被外界静压挤压至临界尺度，中性面在几个 X 点骤然撕裂，磁通绳沿中心脊线串联成链。Two relativistic exhaust channels slice through the ash, ejecting tight packets of charge before the islands coalesce.
Solved magnetic flux potential $A_z$ evolution on a 2D grid with localized resistivity $\eta(J_z)$ triggering at high current densities. Perturbing the initial Harris sheet with multi-mode tearing seeded distinct O-point islands that steadily merged via the coalescence instability. Edge activity stayed near 0.339 due to sharp separatrices, while density variance remained tightly pinned (~0.0001) as the kinetic exhaust successfully carried away dissipated field energy.
