-This Section presents the various **solvers** developed to solve glaciological applications using the finite element code Elmer. A solver is a fortran procedure that solve a differential equation on a given domain for all the nodal variables belonging in this domain. Very often, this result in solving a system which. So time, when the equation is only local, this can be done more simply by iterating on all the nodes of the domain. +This Section presents the various **solvers** developed to solve glaciological applications using the finite element code Elmer. A solver is a Fortran subroutine that solves a differential equation on a given domain for all the nodal variables belonging in this domain. Very often, this results in solving a linear system. In certain cases, when the equation is only local, this can be done more simply by updating and iterating over all the nodes of the domain.
