was trying to use dolfinx_MPC to apply periodic boundary conditions together with Dirichlet bcs, something like u3 = u2 + u4, with u4=10. However, the results show that only part of the Dirichlet BCS are applied. Can create_general_constraint be used with fem.dirichletbc together? Same codes are a…

Issue when apply MPC and dirichletbc together

Thanks. Can I use dolfinx_MPC to apply MPC and assemble matrices? Then, once the Jacobian matrices and residual are obtained, then manually apply the Dirichlet conditions. Is it feasible?
