Make sure you do the cast after equation_systems.init();

It pains me to trouble you again but
dynamic_cast*>(system.matrix);
returns NULL!

Please reply to the list as well.
Instead of creating a new matrix, you should cast system.matrix to a
PetscMatrix and then call MatSetOption on that.

Hi
Can I naively ask how "big" the penalty factor introduced here is wrt the
mechanical stiffness?
Have you confirmed that it is (somehow) at least 5-6 orders of magnitude
bigger than the max element of the system matrix?

This is a PETSc error that you're hitting because you're adding new
non-zeros in the matrix. PETSc tries to help you by throwing an error if
you do this, because allocating new non-zeros (outside the specified
sparsity pattern) can slow down your program a lot.
The easy fix is indicated in the PET
Dear Sirs,
I'm trying to make Libmesh work with a simple linear elasticity problem
using linear systems example 4 as an example. I need to force the top
boundary remain flat, i.e. all normal displacements are of the same value
to be computed.
To obtain this, for example to make the displacements f
