Hi,all I come up with a problem when I calculate the gap of Kondo lattice model with DMRG in ALPS, the computer returns: "Site basis for type 2 not found and no default exists." And I am so confused, because the model I use (Model="Kondo lattice") is from the ALPS lib. So, can you guys tell me why this error message shows up? Does the mentioned error come from the model part or the lattice part? Bo-Nan -- Stay foolish,Stay hungry.
