Zhenlin, The petsc configuration I posted was for complex numbers, which is enabled with --with-scalar-type=complex. If you have not removed this option, then it makes sense that you get the error - the data_out classes do not yet support complex numbers (https://github.com/dealii/dealii/issues/2033). Maybe this is the issue?
