Hi Dhananjay,
Thanks for your message. I removed the dof_handler by mistake when I did
the copy/paste.
I still get the error when I run the following code:
--------------------------------------------------------
constraints.clear();
constraints.reinit(locally_relevant_dofs);
DoFTools::make_hanging_node_constraints(dof_handler, constraints);
VectorTools::interpolate_boundary_values(dof_handler, 1, ZeroFunction<dim,
number>(components), constraints, ComponentMask({false, true, true}));
--------------------------------------------------------
