Difference operators are corrected to $O(h)$ near the interface using the immersed interface method, adding terms related to the jumps, on a regular grid with spacing $h$ and periodic boundary conditions. The force at the interface is assumed known within an error tolerance; errors in the interface location are not taken into account.
