I was using a constraint object to apply the boundary conditions and
component mask to deal with hanging nodes and apply x and y displacements
separately.
Now, I want to solve an elasticity problem on a unit square wherein I want
to apply a displacement in y direction on top face and have a pin and
You want to do something like this:
DataOut<2> data_out;
data_out.attach_dof_handler(dof_handler);
data_out.add_data_vector(solution, "solution");
data_out.build_patches();
std::ofstream output("solution.vtk");
output.set_precisition(12);
data_out.write_vtk(output);
Best,

Did you mean
output.set_precision(12);
It gives the following error
error: ‘std::ofstream’ {aka ‘class std::basic_ofstream’} has no
member named ‘set_precision’; did you mean ‘std::streamsize
std::ios_base::_M_precision’? (not accessible from this context)
I also tried
output.setprecision(12)
Sorry, it should be output.precision(12)

Wasim,
I imagine you are calling your setup_boundary_values() function before you
call dof_handler.distribute_dofs()?

Thank you Dr. Wolfgang Bangerth,
I have successfully applied boundary conditions at the extreme node of 1-D
bar but not able to impose it on intermediate points.
I have following doubts-
1. How to check boundary ids and assign boundary values corresponding to
any intermediate node?
2. In the solut
Hello,
I can't identify the problem right away, but here are some tips in
debugging it:
- Does the problem persist if you disable both h- and p-refinement? If
so, than an issue might be that your data structures haven't been
reinitialized after you updated your discretization.
- Do
Thank for your reply,
Actually I just kill this error by writing the code again from scratch. I
think the problem might be "system_matrix.clear()" is missed befor
system_matrix.reinit().

... sadly after some modification the errors show again(I adapt step-29
into this framework(involves FESystem), with matrix-based p-multigrid). I
think the error is not on direct solver, since the coarse matrix is
initialized successfully in Klu direct solver. However the worst thing is *no
