We have investigated superconducting state of a type I superconducting wire solving the Ginzburg Landau equation with finite element method. When a critical current is applied to a type I superconducting wire, superconductivity becomes inhomogeneous. We find superconductivity shows oscillatory structures which are similar to London proposed intermediate state. In the simulations, we impose two types of boundary conditions, phase-fixed and vector potential-fixed. Under both boundary conditions, we have obtained similar periodic structures.
