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. -- Dr. Karthik Chockalingam High Performance Software Engineering Group Hartree Centre | Science and Technology Facilities Council [email protected]<mailto:[email protected]> [signature_3970890138]
