We study the L1-error estimates for the upwind scheme to the linear advection equations with a piecewise constant coefficients modeling linear waves crossing interfaces. Here the interface condition is immersed into the upwind scheme. We prove that, for initial data with a bounded variation, the numerical solution of the immersed interface upwind scheme converges in L1-norm to the differential equation with the corresponding interface condition. We derive the one-halfth order L1-error bounds… CONTINUE READING
