I also thought this might be a possible solution. However, in computing the stress update, the old stress values are required, which are stored on the old quadrature points. > As Markus suggests, if you are only interested in transferring the > stress state and the problem of interest is linear elasticity then the > easiest is simply to reconstruct the stress from the nodal displacement > and the resulting strain field at the quadrature points of the new mesh. By reconstructing the stress, do you mean interpolating the old stress on the old quadrature points to the new quadrature points? > If you really had internal variables related to some inelastic process > that had their own evolution rule (e.g plasticity, damage, > visocelasticity, etc.) then you have to do something different.

I'm currently only looking at linear elasticity, but may eventually want to look at plasticity as well (this is a long way down the road though).
