In this thesis we analyze one-phase Stefan problem, boundary problem with moving barrier, which is moving due to heat transfer. Stefan problem is process of a melting of ice; and mathematically, it is heat equation with initial and boundary condition, and condition on unknown barrier between water and ice. Due to monotonicity and invertibility of the moving barrier function, we could transform Stefan problem in parabolic variational inequality, for which we showed uniqueness and existence of solution in Sobolev space, which is also explained in detail. In the end we form discrete solution by means of finite element approximation, and give some results on stability and convergence for numerical solutions.
