| This Section presents the various **user functions** developed to solve glaciological applications using the finite element code Elmer. User functions are used to define boundary conditions, initial conditions or any material parameter which depends on other variables. | This Section presents the various **user functions** developed to solve glaciological applications using the finite element code Elmer.
