[petsc-users] periodic boundary conditions

[Karthikeyan Chockalingam - STFC UKRI]

Hello,

This is exactly not a PETSc question. I am solving a Poisson equation using finite elements. I would like to impose PBC. I am thinking of using the Lagrange multiplier method to impose them as constraints. Or do you think I could take an alternative approach?

Thank you for your help.

Kind regards,
Karthik.
