Sorry, my bad. It works for BlockVector. However, there is a discrepancy on deal.ii manual.
Below is from the deal.ii manual about SolutionTransfer module: https://www.dealii.org/current/doxygen/deal.II/classSolutionTransfer.html#a1171abf820e35e02304017ef3daeeaa5 """ Although the refine_interpolate functions are allowed to be called multiple times, e.g. for interpolating several solution vectors, there is the following possibility of interpolating several functions simultaneously. std::vector<Vector<double> > solutions_old(n_vectors, Vector<double> <https://www.dealii.org/current/doxygen/deal.II/classVector.html> (n)); ... std::vector<Vector<double> <https://www.dealii.org/current/doxygen/deal.II/classVector.html> > solutions(n_vectors, Vector<double> <https://www.dealii.org/current/doxygen/deal.II/classVector.html> (n)); *soltrans.refine_interpolate(solutions_old, solutions);* """ However, *refine_interpolate() cannot take *std::vector<VectorType>. Only *interpolate*() has an interface for std::vector<VectorType>.
