I'm working on a code very similar to step-18 and I want to refine the mesh after every few timesteps. I can use SolutionTransfer to transfer the solution vector, but the residual stresses stored in quadrature_point_history are associated with quadrature points, not dofs, so I don't see how SolutionTransfer or VectorTools::interpolate could be used to interpolate this vector on the new mesh. (I'm using bilinear finite elements and Gaussian quadrature.) Any ideas on how to do this? Thanks!
