[petsc-users] 3D Poisson Solver with a Periodic Boundary Condition in One Direction?

[Zhenglun (Alan) Wei]

Dear All,
     I hope you're having a nice day.
     I wonder if there is any example in PETSc to solve 3D Poisson 
equation with the periodic boundary condition in one direction. 2D is 
fine if there is no 3D example.

thanks,
Alan
