function Aux_FEM = Init_Aux_FEM(Mesh_Pos,Vec,Base,Diff)

%% Initialize the auxilarly functions for nonlinear problems
% INPUT: Vec: the vector for the fem function
%        Base: the base function for the auxilarly fem function 
%        Diff: the differential information of the auxilarly fem function
%        for use
% OUTPUT: A struct for the auxilarly fem function for the application
