Thanks for your attention.
I try to find the local density of fermions in the ground state of the extended Hubbard model using DMRG with OBC for L=40 , U=0 and V=4 ( density.txt file) but the local density in the ground state must be as localdens.dat file (calculated using the other code). I think that a potential on boundary must be added to evaluate local density in the ground state with OBC.

Why would you like to add that?
I don't understand that you need to add a term to find the ground state, since you will find the ground state of whatever model you put in.

Dear all
It seems that we must put a potential on boundary to obtain the ground
state using DMRG.
How i can add a term as V/2*(n(1)+n(L)) to fermion model in models.xml
Thanks
