And Andrew is the person to go to with these sort of questions :-) Just for completeness (and in order to leave this in the mailing list archives): When you have internal variables and want to get them from one mesh to the next, the natural way to do this would be - to expand these variables that are only defined at quadrature points to a FE field that is defined everywhere - move this field by interpolation to the next mesh - restrict the field again to quadrature points on individual cells There are functions and classes for each of these steps: - FETools::compute_projection_from_quadrature_points_matrix - SolutionTransfer - FETools::compute_interpolation_to_quadrature_points_matrix Hope this helps!
