Lisa, I solved a problem using deal ii and now in the out put step I have problem > exporting nodal stress and strain values. > in each cell I can calculate stress and strains at Gauss points but I > don't know how to calculate the stress and strains at nodes because they > are not continues. > What exactly do you want to do? You can project these quantities to some FiniteElement space or use DataPostProcessor. For the latter one, have a look at step-29 [1] and step-33 [2]. It is easier to help if you can be some more specific in what you expect the output to be.
