Dear deal.ii community,
first of all, a big thank you for all the effort going into this
software.
With reference to step-45, I am solving the homogenization problem with
dealii software.
After drawing a grid for a 3D cuboid cell, a periodic boundary condition
with equal displacement of opposite sides is created. My version of dealii
is 9.4.0
But i meet an error while make run as following:
error: ‘collect_periodic_faces’ is not a member of ‘dealii::GridTools
And my code is attached. I've already added the corresponding header file,
so why do I still have this problem? Could you please give me a debug
direction?
