 function [f]=insert(edof,f,fe)
% [f]=insert(edof,f,fe)
%-------------------------------------------------------------
% PURPOSE
%  Assembel fe into the global force vector f 
%  according to the topology matrix edof.
%
% INPUT: edof:  topology matrix
%        f   :  the global force vector
%        fe  :  element force vector
%
% OUTPUT:  f :  the new global force vector
