In this paper, a Stefan problem from theoretical glaciology with Dirichlet-Signorini boundary conditions is analyzed. The existence of a weak solution for the nonlinear evolutive model is shown by using an implicit time discretization, an enthalpy regularization procedure, and a Galerkin-type method

A general finite-difference marching scheme for the numerical solution of the ice-thickness equation in ice sheets is considered. From this scheme, a variety of explicit, ADI, implicit and over-implicit methods can be derived. These methods are compared for stability and accuracy within the dynamic/
