[FLASH-USERS] Periodic boundary conditions using implicit HYPRE solvers

Dear FLASH developers and users,

I'm trying to use periodic boundary conditions in hydro parameters. However, when I turned on the conduction parameters, the following error occurred.

"DRIVER_ABORT:
 Implicit HYPRE solvers do not yet support periodic boundary conditions in AMR."

The FLASH user's guide says periodic boundary conditions are now supported in implicit HYPRE solvers. I wonder how I could enable this feature in my simulations. I'm currently using FLASH 4.8 and HYPRE 2.32.0.

Thank you for your support and time!

Best,
Hao
