Numerical analysis of a model Stokes interface problem with the homogeneous Dirichlet boundary condition is considered. The interface condition is interpreted as an additional singular force field to the Stokes equations using the characteristic function. The finite element method is applied after introducing a regularization of the singular source term. Consequently, the error is divided into the regularization and discretization parts which are studied separately. As a result, error estimates of order h1/2 in H1 × L2 norm for the velocity and pressure, and of order h in L2 norm for the velocity are derived. Those theoretical results are also verified by numerical examples.
