Dear Libmesh users,
I want to solve the multi-load case problem with periodic boundary condition. because the boundary condiiton is applied during the assembly of the global stiffness matrix and right force vector. If I have 2 load cases, I need to do the assembly two times. Is it possible to only do once assembly in LibMesh meanwhile considering the periodic boundary condition?
Thanks for any suggestions!
