16 × 16 pc zoomed-in image of a filament of the n = 1 cm⁻³ and ℳ = 1 simulation at t = 0 yr and t = 10 kyr. The filament cannot withstand the shock efficiently, but is destroyed leaving behind finger-like structures that arise from the forward shock front into the SNR interior. Furthermore, some high-density cloudlets are formed (circled in black). The arrow indicates the approximate direction of the forward shock.
