Thank you Matthias, I am not familiar with MPS but I will try. But do you know why the the group '/timesteps' was not passed to the funtion "loadTimeEvolution"? plus, All the others models have not defined anything to do with time evolution. best

Hi,
I would suggest that you try the new mps codes, which are more flexible regarding the models. Michele Dolfi can help if you have questions

Dear ALPS developers, I have constructed a new model of 1-D interaction fermionic system with
disorder and this model works perfectly fun in spectrum function and Lanczos methods. And now I am trying to do the exact solution of time evolution, but it reports "Hamiltonian " type not recognized! use 'Spin'...(whatever exists in models.xml before).
Does anyone know how to fix it! Good day!
