I am trying to use the BlockSparseMatrix setup following step - 22. I am able to understand that step-22 has Dirichlet boundary condition on all the degrees of freedom corresponding to displacement components. But I am trying to have the Dirichlet boundary conditions on only some of the degrees of freedom (e. g. all x dofs on the boundary and only one (this one is to prevent rigid body motion) of the y dofs). To do that, I think some modifications are needed in the BoundaryValues<dim>() function and the part where 'interpolate_boundary_values' is used in the 'setup_dofs'. But I am not able to figure out what the modifications would actually be.
I would be glad if I could get some suggestions/reference.
